I just ran a quick analysis on your game, and it doesn't give me a result that is remotely close to 100% best. Here is the screen grab -
I have never scored 100% best but scored more than 90% couple of times. Mostly because my opponents made a ton of blunders in those games. It is relatively easy to find the best move when your opponent can figure out the worst one.
*Correction: I'm an idiot and did something wrong. It was not 100% best moves.
This was a game that started fairly normally, but came to a quick conclusion. On analysis I got 100% best moves (not just excellent moves, but "best" moves). I'm not sure why this worked quite as well as it did, but I'm not likely to play another perfect game ever so I figured I would post.
