MA will soon fall off mortal horses at 30.

I used the same parents, but bred a few foals from them.
Foal 1 had 4196.58
Foal 2 had 4195.06
Foal 3 had 4200.38

Dam had 4173.47 with 72.07 Blup
Sire had 4161.84 with 70.12 Blup

I don't have access to these same horses on the live server as I bought the parents, which were the closest to 70 Blup I could find at the moment so I input the parent's values into the Howrse Plus calculator, which is usually pretty accurate and takes the gains of the GP your working with into account.

According to the calculator, under our current system the foal would have an average GP of 4216.69 with around 70 Blup. Meaning the new difference in GP between breeding at 70 blup now, and breeding at 70 blup under the new system would be about 16-20 points

And had I bred them at 100 blup we would get an average GP of 4224.98, which is over 20 points difference from breeding at 100 and 70 under the new system.

Grant it, I'm not sure how accurate this is, and I'd like to test it some more, but I suppose that provides a bit of an idea, maybe.
In regards to the actions needed to get to 70, both horses above had the 3 skills bolded, were aged to 10 and had 8 wins. So you'll now need to get about 8 wins if you want to reach 70.

Foal 1: 9787.91
Foal 2: 9787.90

Sire: 9787.46 with 70.12 blup
Dam: 9787.55 with 70.12 blup
Under our current Blup system the foal's average GP would be 9788.46, so there is less than a 1 point difference when breeding at 70 Blup. Breeding at 100 blup would be about 9788.63

For reference, our top GP on INT was 9881, but 100 GP off was the closest I could get, but this test would suggest you won't be too affected if you breed towards the top.
I'm working on blupping these 2 to 100 to see some foals from that

The GP on the parents is slightly lower than the two I used in that last one, but getting wins on preprod is a pain so those two aren't blupped yet.

70(ish) blup test:
Foal had 9748.59 GP
sire-9760.5 GP with 73.06 blup
dam-9735.34 GP with 71.52 blup

100 blup test with the same parents above
This foal had 9748.96 GP

We had a .37 GP difference from breeding the parent's average blup of 72.29 to when I bred them at 100. I didn't get to breed multiple foals to see what the average GP would have been at 70 blup breeding

From these few tests (that are massively incomplete) it would appear those working with lower GP will want that 100 blup more than those with top GP as there didn't seem to be much difference between 70 and 100 breedings when I used top GP. Hopefully we'll get some more complete tests run in the coming days and we'll see what the gain loss could be for those who still choose to breed at 70.

Isn't the top GP very affected when you think about it in % ? The projected gain was 1 GP from the parents but the foals got like half of the projected gains = a loss of 50% (!) of GP gain. Or am I misinterpreting your results?

Having to BLUP twice the amount of horses is huge

On preprod when breeding at 70 Blup my foal had 9787.90 GP.
Using the Howrse Plus Calculator, had I bred those parents with our current system, the foal's GP would have been 9788.46 GP. The difference in the two foals bred under different systems was less than 1 point.

I didn't calculate the difference or gain based on the parents' GPs, but rather how the foals differed under the two systems.

Unless that is what you meant as well

...that is a pretty huge difference

I just.
even if you get to 70 blup with the new system, you won't get the same gp gain as you would with the current system. you do more work and you gain less. it doesn't add up.

The difference in gain right now between breeding at 70 and 100 is so small that there isn't much of an incentive for players to shoot for 100. They save their resources and go for less. I'm going to bring back that screenshot I took of the change log that explains the reasoning

The "New Blup Calculation" section is the whole section I'm referring to.

i get that. i just think it's unnecessary to make it harder to get to 70 blup as well. it's extremely demotivating

this is going to be devastating to uni corn teams, on my team we usually blup to 70 bc it uses so many aging points breeding them only twice a day to have only a small chance at getting a unicorn, it is already pretty difficult to get wins with unis bc the uni gp is a lot lower than gp for the overall breed

I understand this affecting unicorn teams, for the reasons gtkitty said. However for teams which are aiming for the top, I don't see how it's that bad. This may be because I normally blup to 100 before I breed, I'm in a KWPN team and there is a 300gp gap between the top 2 teams and everyone else. That doesn't stop us from making progress or getting wins.

The difference is, is that top teams are almost always rushing to keep their place. For them, every second is precious, so having to get 100 blup each time will massively slow them down and could make them lose their place if another team decides not to breed at 100 and chance it to get the same gains.

Yeah... Exactly. Also more expensive, need more time, harder...
I don't see what's so amazing about that. People who do blup on 70 will have it slightly worse and for people that do blup on 100... Well, nothing really changes. And if so, then like Link's Courage says - it might slow them down, which is - again - not beneficial.
I suppose I don't see any point in that change... Let's hope it won't happen

as unicorns are my main focus on the game, this BLUP update does not sit well with me one bit! Like i have said to a few friends it is probably enough to put me off of the GP race with my unicorn team (not that i will give it up). We breed at 70 mainly to save resources as the next blup is not a 100% guarantee. Our ageing points will be eaten alive even more for one... Especially as H'gifts are not readily available to us and for two, even getting 8 wins can be a struggle as unicorns GP isn't as high as the normal riding horse.
I don't think the BLUP should be changed at all... It is absolutely fine just the way it is

I am really happy about the blupping change.It has been so frustrating seeing teams blupping horses to only 30% to 70% blup and get ahead of determined players like myself that spend the time to produce quality foals by always blupping both parents to 100%. I hope this change gets implemented very soon - the sooner, the bettter.

I do understand unicorn breeders concerns though.I sent note to Contact Us expressing my feelings about the blup calculation improvement . However, I suggested that they might want to tweak the system by either having different calculations for unicorns or else introduce unicorn only comps, which would make it easier for unicorns to get their wins.

I do not see it being bad that MA's will drop off mortal horses at age 30. I always blup my horses to 100%. I have found that I have never had to resort to using a black orchid to get a skiller.I usually get a foal with very high ibs after three to five drops. Occasionally the mare is over 25 before she drops a skiller foals, but I have always been able to drop a skiller foal before the health drops to zero percent. I find it is a lot harder to get quality foals with high ibs if the previous generations have not been blupped to 100%. Friends who dont blup to 100% have told me that it often takes 30 breedings to get high ibs.

Also when the BLUP changes happen, I feel like the competitions will be completely clogged by teams trying to get wins, and for stand-alone breeders or people breeding with a partner like myself, it will be much, much, much harder to get wins.

When you are gaining under 0.10 GP per generation I think you will see why they will cut corners when possible. I have seen top teams blup over 100 in a single day just to keep their ranking, that there IS "determination".

I am on 6 top uni teams, and this will not affect us. We breed at 100 BLUP. My teams were like, finally a change that doesn't affect unicorns. I thought all or most unicorn teams did 100 BLUP. There is no reason not to with the 10 hour rule. For top gp, yes, it will make a difference. Unicorns? Not so much. Donkeys...I feel for you!

We don't know yet. We didn't get any news for that since they told us it won't happen until this year. So we have no idea. (Hopefully never, but it's only my opinion.)
