Preliminary Results of Prot Comparison

I've gathered Prot data from 3 sources:

Baliunas 1996 and Wright 2011 - both of which use photometric variability to determine Prot, and Rutten 1987, which uses vsini to estimate Prot (not the best indicator of actual Prot, but a good enough estimation). Here are the results so far:

Obviously, the mamajek code works best for fast rotators, and becomes less precise toward slower rotating stars (most likely K stars).

Here's the same plot separated by spectral type:
