Backlog says it gave 2, but menu is saying 3, I checked because on a pink-only run things are usually always even numbers, so I was wondering if I had accidentally taken a normal scene somewhere. Reloaded prior and was on 0, post was 3. Only thing I can say is that I was using body coating that day to pump magic defense on various sensitivity increases. 

The increases aren't static values, they depend on your fetish/sensitivity focuses and lewdness value. This one has a base of 1, increasing by 1 if your fetish focus is masturbation and another 1 if you meet the "extra lewd" requirement.

Are you saying the actual value was different to the one shown in the log?

I have/had no focuses at that time except for lewd knowledge for magic attack.

I think I've found the cause of the issue, one sec.
