Darky,

It's amazing how similar it is to what I do except I look at the 3rd AND 4th fav and don't ALWAYS back the blowie, sometimes I will back a horse that is coming in, it just depends on odds movements from various sites, and I can sometimes let 10 races go before I find a bet.
Today was my perfect day M2 crepes and I got $2 place fixed odds.
1 bet, half the average weekly wage and finished.
I love it.

Cheers
