efficiency

Hi,

Efficiency = (winnings-losses) / (winnings+losses)

It's not number of wins but amount.
So it takes into account your liability.

Hi,I think that would be called profit on turnover.

efficiency tells you if your strategy is spending too much to win too little. The closer to +1.00 you are, the better your strategy is (its efficient). The further away from 0 towards -1 you go, the worse your strategy currently is ( its inefficient).

See attached, 15 wins, 8 losses, efficiency -0.00. So the loss on the day1 of -6.80. Not so good but the strategy efficiency rating tells me its worth pursuing. So on another day with a better run I get 17 wins, 6 losses, efficiency is now 0.14 with a profit of 21.68

yes, if you can maintain that strike rate

The Srike rate says noting you can lay at odds 100 and you will probably win 50 in a row.

He's obviously not laying at 100/1 if he has 2 losses from 13 and a healthy profit, so to say strike rate is nothing is incorrect in this instance, and indeed in most. Anyway, not getting into that whole s/r thing again. The point is efficiency of +0.30 is good

Thanks everyone,i prefer to look at strike rate but then i'm not as clever as you lot.
