Okay even though I have spent and will spend more countless hours on FFX, there is still one thing I do not know.

And that is as the title says, are the stats really maxed out at 255? Obviously on display they are but is it actually possible to raise them even more by adding more spheres on the grid?

This is something I read a while back on many forums but I never found definite answer as for if they are or aren't maxed out at 255. This would obviously only be possibly useful for strength and more importantly, magic. Not that it is really needed but still is it possible?

Stats are a little weird as in Agility is pretty much really maxed anyway.

Anyone knows for SURE which is it?
