Hi wesmip1,
I just tried to edit my last post but must have taken 5 minutes and 1 second. I wanted to insert the following paragraph or something like it:

"If they're of any use the results for winners only are:
Before change 31 winners - total 0.852
After change 30 winners - total 0.815.
At least the exercise increased my total of winners by one but the nett return stands."

Cheers
Ron
