How did you treat crits? The app doesn't count them in normal hits. I do no know whether it is calculated before or after parry. I have some data suggestive of before but nothing definitive.

There is some very odd things going on with these numbers assuming that, like block / parry mitigation, FFXIV only uses two decimals for rates. #5 really just doesn't fit. With the prior mentioned assumption, it looks like you cross three dex thresholds which I don't think should be possible given #2 results (not impossible, but unlikely). A possible consideration may be that Dex and Parry rating are not treated separately for the purpose of determining the rate. Although, that makes #2 hard to reconcile.
