Information from Layability about their service

At Layability we think that the safest way to lay is to a fixed liability. As our general odds range is from 5.0 to 7.0 our biggest liability is 6/1. This means that you can follow this service with a losing liability of just £12 upwards (Betfair minimum bet is £2).
We recommend that you use 5% of your bank as your total liability and increase that liability as your bank improves.
We expect to get nearly 90% of selections right so betting 5% or a twentieth of your bank will really smooth out any of the losing runs that occasionally occur. It is worth noting that we also have very long winning runs often well in excess on 20 winning bets.

Bets = Number of selections provided
SR% = Percentage Success Rate. i.e. number of profitable selections / number of selections
Staked = Total amount risked on selections, based on amounts entered by the tipster (e.g. a 10 point bet placed at odds of 4/1 would be a stake of 40 points as that is the amount you'd lose if the selection won the race).
Profit = Total points profit/loss. For 2008 onwards Betfair Starting Prices are used. For years prior to that, odds of 15% above SP are used. The figures assume a commission rate of 5% on all winning bets. This is an upper amount and will reduce the more bets you place with Betfair. You can see the effect of varying the assumed commission % by looking at the Full Proofed Results (see link above).
