I am pretty sure that Admin, binary, spudilike, or any other fans who usually make the growth charts have not made one for V4.5 yet. V4.5 is very new so there really is not much data for anyone to make a growth chart with yet. Though, I think someone on Tamatalk is trying to make one...maybe you should consult them.
Hope I helped,

P.S.Oh, and, hea10k, the V4.5 growth chart will NOT be the same as V4 one. Though, I can see why you would think so, because V4 and V4.5 are so alike. But the V4.5 has totally different characters, skill points, and family groups-which means, the growth charts will have to be different.
