Horse breeding rates

Hey,
Horse breeding rates seems not really accurate and we are not able to get any t8.
If you want to get the same breed rate as retail.
Here is how somethinglovely determine tier :
They define grades for each horse:

example for t8: grades[maleTier] = 620 if your horse is level 1 and grades[maleTier] = 650 if he is level 30

Then use that:
((grades[maleTier] + maleLevel * rate) * (100 - maleDeaths * 0.5) + (grades[femaleTier] + femaleLevel * rate) * (100 - femaleDeaths * 0.5)) / 2 / 100
example for a T7 lvl 30 0 death male and a T1 lvl 30 1 death female.
((975)*(100)+(555)*(99.5))/2/100
-> 152722,5/2/100
->763,6125
breeding = 763,6125
Here is what breeding mean:

with 763,6125 we should be between 455 and 600
now use that list:
https://pastebin.com/0Ed86Rf8
The result should be between t5female and t7 female

Now they determine the %.
lets say we want to know the % for a t7 male:
our breed grade is between 455 & 600
min = 455 & max = 600
a t7 male is between 555 & 585
g.min = 555 & g.max = 585
if the number for the t7 is fully contained in our breed, mean that [555;585] is fully in [455;600]
we use that :
(g.max - g.min) / (max + 1 - min)
-> 30 / 146
-> 0.205 * 100
-> 20.5%
lets check on something lovely : http://i.imgur.com/cu3NPrY.png
but if the tier is not fully contained and only the max is in:
ex:
your breed is [435;600]
and a t5 male is [425;455]
[425;435[ is not in your breed.
Then you use that:
((g.max - min) / (max + 1 - min)) * 100
->((455-435) / (600+1-435)) * 100
-> 12%
--> http://i.imgur.com/6VG0yRA.png
we can see thats its really 12%
Now if the min only is on your breed value.
lets say your breed is [495;630]
and the t8 male is [620;650]
then only [620;630] is on your breed.
Use that:
(max - g.min + 1) / (max + 1 - min) * 100
-> (630 - 620 + 1) / (630 + 1 - 495) * 100
-> 8%

Well, I'm done here explaining how somethinglovely find his tier / percentage for every breed simulation.
I hope it will be useful to get retaillike breeding rates on the server.

TL DR:
You need those ressources:
https://pastebin.com/TJD4J8ch
https://pastebin.com/a2JrAsEd
https://pastebin.com/0Ed86Rf8
example for t8: grades[maleTier] = 620 if your horse is level 1 and grades[maleTier] = 650 if he is level 30
Determine the obtainable tier with :
((grades[maleTier] + maleLevel * rate) * (100 - maleDeaths * 0.5) + (grades[femaleTier] + femaleLevel * rate) * (100 - femaleDeaths * 0.5)) / 2 / 100
Determine the %
if fully contained
(g.max - g.min) / (max + 1 - min)
if only the max is contained on ur breed value
((g.max - min) / (max + 1 - min)) * 100
only the min
(max - g.min + 1) / (max + 1 - min) * 100

(All those ressources have been found on somethinglovely sourcecode)

 

I strongly agree with the need of changing the horses. It may not be the most important thing to do right now on the server but horses are still a major part of BDO and the stats scaling is a mess.

 

I was going to start a new thread suggesting the increase in rate since http://www.somethinglovely.net/bdo/horses/ recently added the adjustable horse rates.
From all my T7Male T7Female attempts and after talking to a few horse breeders, it seems like we're on a breeding rate of 9, which has 0% chance of t8. Even bumping this up to 10 gives us at least an 8% chance for a t8 (which no one on the server has bred yet).
I think we should be at least on par with retail (breeding rate of 13), if not higher, since this is a private server after all.
