So instead, the crit cap would be 100%-glancings-miss chance (since you shouldn't have any dodges due to expertise, I'm just gonna leave it out).
P.S. For chance to miss affecting it, easiest way to explain is: you can't crit what you can't hit, so if the attack you make wouldn't "hit" the target, it can't crit it either.
