The strike rate of favorites are directly proportional to the price. It is indirectly proportional to the number of runners. Distance and track conditions are reasonably even. Something that I cannot check at present is class. Having said that I have noticed that in maidens and lower class races the favorite strike rate per price range belies the average. More $2 favorites fall in lower class races than $2 favorites in opens.
I hope this helps. Beton
