And your requested extra:
Top CP combined with Top Final Rating DS and barrier >= 5
6678 selections returned 5673.40 on tatts.com (15 %loss)


Barrier 5 improved it but only by a few percentage points.

I remember reading from Wesmip1 post back in 2011 giving the following results

1. Top CP rating
2. Top Don Scott Final Rating
3. Barrier 5 or wider

Profit on Unitab Prices = 2.6%.
Sample Size = 935

The profit on the above on betfair prices (assuming 5% commission) is 20%.

Why aim for 5% profit over 1000 bets (the so called professional profit) when its possible to pick up 20%.
