CP I have a query that you may or may not be able to answer but I didn't really want to start a new thread as I figure its possibly a pretty simply answer for someone who has the data available (possibly yourself).

I'm looking at implementing some systems and I recall someone saying top tote is better than betfair SP in about a 65%/35% ratio or something similar. My query is at what point does this becoming approximately 50%/50% as I assume betfair SP is best once you get to longer shots.

i.e. is there a point where you can dictate i'll place top tote bets below X and betfair SP bets above X. I was thinking somewhere around the $15 or $20 mark would be appropriate but someone may have a more accurate answer.

Cheers
