@Purple:
They're just that. They're just numbers meant to fit a little bit but I really don't think they're supposed to be taken too seriously. They fit in enough ish to show some stuff like small comparisons like the three kids aiming to be generals but warfare is never so simple to chalk it up to numbers, especially when the author needs to keep up a continuous narrative. And once you get into the 90's or so when the cap of anything is 100 it really is hard to believe that no one is capable of surpassing someone like Houken. Like, a cap of 100 just seems incredibly arbitrary, and anything in the scale of 90's is probably already impressive, so why use them as hard numbers to say "oh, he or she only won based on this particular stat"?
You shouldn't use them as concrete fact, but they're relevant. And 100 isn't really the limit Houken is actually 100+
The stats are still good to reference since they give us a general idea of where the characters are, I don't really use them to decide who will win a fight/battle/war. It's just one of the factors that I consider.
