Out of interest there was one accident from the seven selections mentioned in the original post.

If $30 had been layed on each selection assuming the S.P. price was obtained, then the profit would have been $19.80. However, laying them for the minimum of $30 on S.P. the profit (which I fortunately made) was $79.57.

I made a mistake with Saturday's results. One of the accidents was Rosehill R3 no.8. - Pane in the Glass. There were only 8 starters in the race which means it was not a genuine selection. So there was only one accident.
