It's good to compare numbers. You have over 4000 trophies, 50 Platinum. I have 1500 plus trophies but only 5 platinums. Your ratio of trophies to platinums is 1.25%, mine is .33%.
Majority of games, I just don't bother platinum and the ones I do are usually easy (or I got loads of trophys anyway and just finish the last bit).
Hmm, pie.
