What ever you have read in racing for the last 200 years is wrong.
That is my point.
Not 50 races, not 50,000 results but millions of results.
So any banter about video replays, speed maps, jockeys, trainers, track bias, on and on and on, moan,
moan moan; does not effect the result of a race more than how fit your bet is behind the stalls.
