Mark,

I think this is what you are after. I dont have as much data in the database as Felicity so this is from the last three years - just under 4000 meetings (all days).

Race No/SR/Avg Runners
1 - 71% - 9.65
2 - 68% - 10.26
3 - 69% - 10.45
4 - 68% - 10.41
5 - 66% - 10.52
6 - 62% - 10.72
7 - 61% - 11.19
8 - 60% - 11.62
9 - 59% - 11.91
10 - 57% - 12.18

So Race 1 is won by a runner in top 3 71% of the time and has an average of 9.65 runners, etc. There are not many races 9 and 10 so you may want to ignore these figures. Also the top 3 in my database is based on Tabcorp final price (not the bookies SP) and horses equal on price are ranked by saddlecloth number (so the above figures do not account for equal 3rd favs).
