Interestingly, I found this post from 2003 by osulldj:

ODDS ON FAVOURITES METRO ONLY, ALL DAYS SINCE 1/3/99 to 31/5/03 (4yrs 2 months)

Selections: 783
Wins: 412
SR% = 52.8%
POT = -10.4% on turnover

Interesting that after 10 years, since this was posted, the SR% hasn't changed a bit! The only thing that's increased over the years is the LOT, another 1.83%, and the LOT trend will probably keep sliding into the future. What do you put that down to, more people betting due to the advent of the WWW and online bookmakers?
