NO

He has won 10 out of 12 races so far. He has 10 more to go. Let's call his chances of winning a race 10 in 12, or 0.83. With 10 races that gives a 0.83^10=0.16, so 16% chance of winning all of the other races.

(11/13)^9 = 22%

(12/14)^8 = 29%

on the bookies his odds for the next one are -300 (75% chance of winning). There are 14 races remaining. 0.75^14 = 0.0178. I expect black swans to disrupt his dominance rather more than enhancing it.

Where did you find the odds/how do you calculate the percentage? I'd expect his odds for a single race to be a bit better by now
