Yep those were the days all right. I learnt a lot from your sheets but one thing has me stumped to this day and that is web scraping. I've tried altering your code to import from other sites but too big a dummy I'm afraid. As I said I use the market with my ratings and I copy and paste from Puntingform for that. Couldn't get it any other way.
I use six systems divided into two groups and if the two groups agree on the top two selections and are are six points clear of the 3rd selection it's a bettable race for me. For instance I've got in order 1&3 in Seymour Race 9 and 3 is 6 clear of the third selection. As you see 1st and 2nd Fav.
