I was looking through X-Act's article on PID info, and I was wondering if I was understanding it correctly, or if there was a mistake. The numbers listed as benchmarks for gender determination don't return the correct percentages. Assuming it's right the gender ratios should be 12.1% F, 25% F, 49.6% F, and 74.6% F.
Assuming that the gender ratios are in fact correct the max values for female pokemon should be 31(30 in the article), 63(same as the article), 127(126 in the article), and 191(190 in the article). Has anyone tested these numbers to see if they return male or female? I'm about to do it myself, but if it's already been done then I can save the effort.
My first thought is that the article (and actually RNG Reporter, since I used the information directly from the article) are both currently incorrect. I think the numbers should be (same that you came up with):
31
63 (currently correct)
127
191
I went to bulbapedia to double check and it turns out there is a (different) error there, which confused me for a minute. Anyhow, ingame verification would be great, if you can. Once we get that straight, I will update the article on site and release an interim RNG Reporter. Sort of surprised this has not been caught yet with a "hey, I got the wrong gender!" post.
