Charisma does have an effect on the initial cast of charm

I found no evidence of that. Resist rates on the initial cast were equally high in both conditions.

That coupled with your significantly less data for the 115 CHA testing could explain the difference. I'd advise testing on a mob with less MR, as MR will affect charm breaks quite a bit. That specific mob you are testing is going to break quite a bit probably due to it's MR whether or not CHA affects charm breaks, which can muddy the data.

The number of trials compiled only affects the sensitivity of the test. The relationship between sensitivity and number of trials is effectively an inverse square law:

Sensitivity is, as a rough estimate, around twice the value shown in the graph. So the 1100 trials used for the EJ Spurbone gave a little under 2% sensitivity. But it rises rapidly for lower numbers of trials (this is one of the benefits of the Wilson Score). This test produced 92 tick-trials for the CHA115 condition and 457 for the CHA226 condition, and after adjusting for the change in p_hat this gives a sensitivity estimate of around 10%, comfortably under the difference that was found. So I feel confident in the result.

The goal here was to test on a mob with a fixed level that was easily accessible to allow repeatability. If you can think of another candidate with lower MR, please let us know.

There probably isn't a level 50+ special check of some kind, there's no evidence of that in the EQEMU code. Unless someone has a P99 patch note or some in-era evidence of that.

I think that, after 10+years of operation, it would be an error to assume that the code running p99 is identical to the EQEMU base.
