Returning to yesterday's discussion on the advantages of playing high volume: I used 70% vs 60% win rate to highlight the discrepancy in return. A more realistic example would take a player hitting 55% vs an elite handicapper of 65% releasing a highly selective card each day.
If both begin with $1000 and the elite handicapper has 20 plays a month against the 55% player that has 100 plays per month this is what ROI looks like if they average $10 per wager:
1. (+130 - 77)/100 = 5.3% ROI
2. (+550 - 495)/100 = 5.5% ROI
As was mentioned, a 5.5 ROI is very useful over the course of a year. If we are trying to use real world examples the hurdle for volume players is maintaining sufficient capital to play the entire card each day. Do I really want to put 30 playes in on a NBA/NCAAB/NHL/Martial Arts/Soccer/Horse Racing Saturday? For me yes, but this isnt always commensurate with my available capital.
Ultimately, this comes down to picking winners. If you stay on the right side of 52.7 either approach yields the desired outcome. ROI becomes increasingly important when accounting for exotics, futures, moneyline parlays etc.
Best regards.
