I think people are just using whatever settings they have and are filling in the list. I can’t be certain, but that’s what I believe is going on. For example, there were a few games in there that are listed as being slow in the comments but are listed as working, that are not at all slow for me.
Whenever I update the list, I try to give a little wiggle room for performance.
I believe most people don’t want to void any warranty they may have on the PI, and are sticking with 1000 mhz. For me, I view the cost of the pi as pretty negligible, so if I blow it up with the aggressive overclock, I’ll just replace it.
