Your game must be pretty long but in the stafford, white usually gets a advantage in he book moves
how come i didn't get 100 percent accuracy?
I had the same question some time ago: have a look: https://www.chess.com/forum/view/game-analysis/the-question-is-why-not-100
when i did the stafford, i had the same thing. 99.7 accuracy. very weird. I played all the best moves
