I haven't gone through all the tests past the second half of page 2, but I noticed no one is accounting crits. Crit attacks cannot be blocked or parried. This makes game table precedence as follows:

Miss > Crit > Block > Parry > Hit.

I think you would get more accurate results if you also remove crits from total hits landed.

Tests done were:

1. Use Sheltron, crit lands, Sheltron buff STAYS. Next hit blocked, Sheltron buff goes away.

2. Raw Intuition: Parrying attacks, still getting non-parried crit from the front.
