I have been able to breed some horses with good potential ratings. About the best I have is 75% total, with a dark green of 70 %. I can't seem to get above that, and it only comes along about 20 % of the time.
Does anyone have 100% potential rating in SO7. Is it even possible, and how did you achieve this?

The only way to improve the potential in your horses is to breed with gamebred stallions in the breeding barn.

I have had so many saved games crashing on me that I have experimented with new saves to find the best way to start a new save and find good horses. I suspect that the same concepts would work in the middle of a game.

Step 1
When you start a new game, set autorun years to 5. It takes about 10 minutes on my computer to start the saved game. On easy level the 5 horses I get on startup are usully poor, doesn't matter, I just auction them off.

Step 2
Look at the stallions in the barn. Usually one or two stand out. They will probably have bred over 30 x G1 winning horses. These are the horses to breed with.

Step 3
Save the game and make a copy of it to usb.

Step 4
Use the "betting cheat to get about £20million.

Step 5
Buy all the stable improvements.

Step 6
This next step is very laborious and takes time. I visit every auction, both daily and weekly. I buy every single filly\mare that comes up for auction. I am looking for mares with 50% potential as 3yo, 75% potential at 6yo. Every other horse is re-entered into the next available auction. When I find a suitable mare it is sent to the barn and bred with the best stallion, probably no more than about 4 stallions.. Over the course of a season I find about 20 - 25 such mares.

Step 7
A few days before the end of the season save the game.

Step 8
Go on to next season and look at new foals. If you are really lucky there will be a good colt, but I am looking for two things. Fillies who are better than the mares already in the barn and which stallions sired them.

Step 9
The next step is dependant on the best stallion in step 8 still being in the barn. If it is not, try repeating steps 7 & 8 above using the backup of the game.
Breed the best fillies from step 8 with the best stallion. This results in a little in-breeding but after about 7 - 10 seasons I have a whole stable full of high potential horses.


One last thing, for some reason in the new games I have started, it has been sprinter stallions that this has worked best with.

I have just started a new Combined game that is 11 seasons old and this is the result.
