Thanks very much wesmip1 for the 2 files. They are very much appreciated.

I have a stupid question (which may probably qualify for the stupidest question on here, ever) which I think I would normally have the answer for but I think my brain's fried as I'm coming to the end of my 2 weeks holidays tomorrow.

Going through some data supplied by wesmip1 I've come across the following:

This is for backing with $1 level stakes
Selections: 1131
Winners: 205
Losers: 926
I take it that's a 18.1% strike rate.

Now comes the part I'm not sure about.

The winners have paid 1110.55 on Betfair.
Taking away the 5% commission takes it down to $1055.03

Now, do I take away the $1055 from the number of selections (1131) or do I subtract the losers ($1 x 926 losers = $926) from the winners ($1055)?

If from the selection numbers then this is a loss but otherwise it is a $126 profit (which isn't much for the amount of selections but at least it's something).

Basically, I think I'm getting mixed up about when to add or subtract my $1 stake for each selection.

I would be grateful for any for my fried brain. Thanks.
