Has Anyone Ever Bred A Significantly Higher Potential Than Parents?

So I know that whenever you breed, the game lets you know that the potential when breeding two horses is 50 less than the lowest potential and 50 more than the highest - and I'm genuinely curious, has anyone ever gotten even close to the highest possible potential?

Even before the weird update, the most I got was 20 above, and after the update I'm super lucky to get, like, 5 above. Do you guys think it's even written into the game's program anymore? Has anyone won that breeding lottery? lol
