I'm sure someone who specialises in locking themselves into a darkened room, poring over thousands of Excels, would eventually concede that if 500 people picked a horse based on any of those criteria, then all of them would be right at some point. I have raceday colleagues who are almost as demented over ratings and times as some members on here, but they were in the company of a non-racing female friend of mine a few years back at Brighton, when she picked - a winner, because it's owned by Mystic Meg (and she's well into astrology, Tarot cards, etc.); a No.8 which won - because she's very friendly with some London Chinese people, and it's considered to be the Chinese's lucky number; Nos 2 and 4 in a race of 7 (no 8 available), because - youv'e got it - 2 x 4 = 8; a horse with a name that sounded a bit like her Mum's, and something else based on the same criteria. She took home just under £1,000 from the Tote, her outlay being about the price of a tray of chips. My oh-so clued-up raceday friends? All about £3 down to £12 up on the day.
I won a tipping competition on another website, quixotically based on the names of horses related to alcohol or Africa - cue wins from FAMOUS GROUSE, TABLE MOUNTAIN, et al, and a nice prize for me.
The facts are that you might just as well go with my own theory of the No.1 horse winning the first and the No.7 horse winning the last more often than not (try it - it's true!), back Joe Cole's POPPANAN because you love your grampa and nanna (hence his horse's name - which won today), or go in large on No.8 in race 8 (especially if it's on August 8th). As many times as your wodge on the odds-on goes straight down the pan, your timid little fiver e/w on the 33-1 shot called I'm With Stupid will hack in 2nd or 3rd.
It's no doubt all down to the law of averages or something, given the number of horses running at any given time throughout the year. But don't be too quick to diss what works as often as anything you've spent 10 hours doing ratings for!
