Wennejoekel Hi, you don't compare your own rock, paper, scissors stats, you compare it to your opponents. F.e. I had 12 food, 8 rock and 13 science. I compare 12 food vs my opponent science, my 8 rock vs opponent food and my 13 science vs opponent rock. So it's possible to get +99. You can check the google spreadsheets for examples as some games have finished.
This doesn't mean your opponent can't also score bonus points btw, in my game it was f.e. +99 & +33.
