Okay, I've seen this on practically every single PSP forum out there. Those "devs" (as they like to be referred as, so I shall do so) with 1 to 10 posts frequently tell people that they are "20%" or "38%" done finding an exploit. What does that even mean? It's either you found an exploit or you didn't. You can't scale progress because it's either you found it (100%) or not (0%).
I speculate that those who do so should be castrated. 8D
