just fyi i think the usage stats script for items is bugged around knock off hitting into rocky helmet or less likely just hitting into helmet in general. I don't think it's possible that 33 gurdurrs in bossaru cup used helmet, plus 3 raticate, 2 sneasels, etc. since it's pretty much only mons who click knock off who have the random helmets popping up that's why i think it's that interaction.
