I wonder if anyone who's been jockeying for best prices for a while could give a few tips to an amateur.
I've been running half a dozen screens for a few weeks now balancing the three tabs and best div against the fixed price offered by various online bookies looking to get the best price about my selections. Are there any golden rules for this sort of thing?
I had a horse a few days ago which was real short with the bookies and much longer on all three Tabs so with about ten minutes to go I said "Buggar it, I'll never get a better fixed price", plonked on the best div and went and made a cup of tea. Lo and behold the horse paid 1.90 best div and the bookies finished at 2.55.
The only general trend I seem to notice is that real short favorites on the Tab, like 1.40 to 1.80 ish seem to lengthen in the last few minutes and favorites about the 2.50 upwards seem to shorten. I'm guessing the mass of favorite backers plonk on the favorite if it's long enough and don't bother if it's too short.
Any general advice or observations on the science of getting the best price would be greatly appreciated.
