So, I don't know if this issue has been brought up since I didn't have time to read all 10 pages of this topic.
Today I have been spending some time calculating some average stats for Awakening Characters without factoring in Second Seals and such (for the most part). I went to calculate stats for Owain as a Dread Fighter and discovered the Growths for him as a Dread Fighter didn't exist. So I decided to calculate them myself. After doing that I compared the stats I got to Owain as a Myrmidon to make sure I had the correct base growths.
What I calculated didn't match the page at all, and upon further research, it doesn't look like the growths of the children are calculated correctly when taking into account the Avatar's Asset/Flaw. It seems to be changing the growth by the full amount of the asset/flaw instead of just a third of it, like it should be (unless this is how it should be, though that doesn't make sense to me).
What the site shows for Owain having the Avatar as a father with Def as Asset and Luck as Flaw followed by what I calculated by hand:
HP, Str, Mag, Skl, Spd, Luck, Def, Res
80, 50, 28, 61, 60, 51, 45, 38
80, 53, 31, 61, 60, 55, 35, 35
The five stats that are off are the ones affected by the Asset and Flaw.
Shouldn't be too hard to fix if it is wrong I hope.
