I've been wondering about this for quite sometime, and I finally decided to take screenshots to make sure I wasn't crazy or miscalculating. When rolling, the lowest stat is supposed to roll twice in a year, correct? Well, when you get past about 185% or so, it takes longer and longer to roll.
I took this screen shot the turn Intelligence hit 167%. Note the age of the horse and the turn number.

The stat, despite being the lower stat, took 16 turns to roll. versus the 10 it should have if it were actually rolling twice a year.
Is this supposed to happen?
