Morning!! What's going on with all Sahasastar's replies (52-55) to posts which are NOT THERE??? Anyway, when it comes to "systems", I start betting when I genuinely believe I'm onto something (there is no "trial" period of waiting and watching). This means noticing something "odd" and quickly scanning a few records. If this oddity shows up again and I can explain it (to myself) then I BET it continuously, immediately. For example, let's say I notice that a number of Stable A's horses have been winning with Jockey "X" aboard and that they are paying well. I quickly note that this has been the case for at least the past 3 months. I ask myself why this is happening (especially if "X" is not the most accomplished jockey riding Stable A's nags). Is it "random"? I discover that "X" is the stable foreman's nephew (sound like a Melbourne Cup winning hoop now riding in England????). That's it. a system is born. So maybe it doesn't work out but mostly these "hunches" DO, until the rest of the punters wake up to "X". This principle (bet immediately) is the "best waves" surfing theory in action.
When I would go surfing I noticed that snap decisions (if soundly based!!) were best. WAITING for several great waves to go by BEFORE jumping on often meant missing the best rides of the day. You were consequently sitting out the perfect breaks and leaping aboard the "duds", experiencing the troughs, losing confidence, and then seeing ANOTHER "pipeline" go by while dithering. My advice is BE BRAVE and trust yourself to be on the Crests, in the surf and on the punt!!
