Thought this was answered on the other post but here goes.
Most bows are 1/8-3/8 pos tiller,which means more length on the top when measured from the fade to the string.These bows can be shot split or three under no problem just by adjusting the nock point untill it tunes properly.
Some bowyers don't bother with changing tiller for three under or split as they don't think it really matters.Some do change tiller and it is usually even tiller for three under.
On bows with adjustable tiller archers shoot anything from 3/8 or a little more pos tiller to just as much neg tiller.It depends a lot on the shooter and his release.Some think tiller matters more than others.
I wouldn't be worried about a quarter inch difference either way, split or three under.I know you want to make sure your new bow is built correctly but your release will effect arrow flight more than that quarter inch IMHO.
Good luck
