Any Statisticians out there got statistics for 1st and 2nd favourites only?

I know that about 25% of outright favourites win, but about 70% of winners are under $6.00...roughly.

I am inclined to think 40-50% of winners are either 1st or second favs.

For Example, last Saturday out of 75 races I checked 31 winners were either 1st or 2nd FAVS (TAB PRICES) giving 41% strike rate. I don't know if this is typical though, to get an accurate picture you would have to run it over at least 1000 races.
Any stats?
