Ok, did some math (spreadsheet). Not going to post it, because formatting looks like shit. That being said, I took the numbers (striking accuracy and striking defense) of all women in the ufc, and ran then.
In terms of striking accuracy, Miesha is 31st out of 60 women sampled. In terms of striking defense, she is only 23rd, which surprised me at first, then I remembered how bad striking defense is for so many in MMA, and apparently even more so in women's MMA.
Over the weekend, I may do a proper statistical analysis, and eliminate things like one-off fighters who will skew the data, women who are no longer on the roster, etc. and put it up somewhere. I think I still have an account with Stack, not sure, I do very little web publishing any more. But it is actually fairly interesting.
(women with highest combined numbers is Waterson), lowest is someone who should not be there. So it needs cleaning up. (not super-anova but there is simply crap that should not be there that distorts the picture slightly).
End result: Miesha is middle of the pack, striking.
