Am I misunderstanding something here? 0,92 RPPM means that it proccs once every 65sec, so with a 90sec setting on pull it got 25sec over this proccrate, that would mean it already got an increased proccrate on pull.
And BTW, I guess you misunderstood the wording "procc protection", since it doesn´t mean that it can´t procc before this time is over.
Lets say Trinket XYZ got this RPPM of 0,92, so it proccs every 65sec. So lets say it got a 50% chance to procc in the first 10 seconds of the pull (attention: It´s NOT 0!!!), that would mean with a timer of 30sec it got a LOWER proccrate (lets say 25%, I don´t know the actual formular for this calculation, but I can post it for you after work if you want to
), and after a timer of 130 sec it got a HIGHER proccrate (100% for example).
Trinkets ALWAYS have a chance to procc and it´s getting higher the longer you havn´t got a procc
