On The Bridle
At the Start
Seriously good read....a must for anyone who wants to make a profit betting. I know a few here have read it already....I read it this evening. Excellent insight to the mans thinking.
Yes, and I wouldn't be surprised if the title of his new book is a middle-finger to, and a parody of, the influx of muppets on there with their regular catchphrase -- "It can't be done".-once upon a time you could read his thoughts on the Betfair forum Irish sports section -until the lunatics took over the asuylum.

what is exactly being "done"...making it pay for 20 weeks?
The blurb I read said "made A fortune in 20 weeks".
Rarely buy racing books, but I've long felt that punting psychology has more bearing on success than staking, value seeking and the host of others many pay lip service to, and I ordered it this morning.
Got it on order. It won't be as good as Alan Potts' but I hope it's better than the Nevison one I read a few years back.
Really? I've heard him on a couple of podcasts talking about NH.
He mentions in the book that he loves NH and follows/analyses it but doesn't bet seriously on it. Too heavily analysed by others for him to find a consistent edge.
(You did ask)
I've only read the first 4 or 5 chapters so far so I don't know if he goes through it in detail later, but based on the proofed results at the back of the book:
He only had 56 bets, so normally you'd think "small sample size!" but you have to remember that he specifically chose the bets from a potentially massive number of possible bets. That's his skill; narrowing down the opportunities and rooting out the value.
He backed all but two of them for £1k, so he gave each selection the same value; we don't need to take into account the idea that he was more confident in some than others (even if that was actually the case). They all passed his threshold for what constitutes a bet.
13 of the horses won. It so happened that the 13 winners gave him a profit of £44,500.
So lets say 13 winners was his true strike rate (more on this later). That, given random chance, his skill allowed him 13 winners from his 56 selections. Where random chance comes in is *which* of the 13 winners would win.
How many different ways can you have 13 winners from 56 selections? Just short of 2 trillion.
Here's the thing - his worst case scenario, in which his shortest 13 bets win, would only have left him with a loss of £1500. So the number of ways he could have lost money with that strike rate (13/56) at the prices he was playing is vanishingly small.
Was he lucky to win as much as he did given that strike rate? I simulated 100,000 trials where 13 of the runners he backed were randomly picked as winners, and the rest were called losers. He wins at least £44,500 around 54% of the time. So actually he was a little bit unlucky in terms of which horses won, but not much. The break-even amount, i.e. the amount he should win 50% of the time, is around £46,000.
So the other question is, was he simply lucky to get 13 winners?
Here are the amounts (to the nearest £1k) he could have expected to win around 50% of the time for a given number of winners from the 56 bets:
13 winners: £46,000
12 winners: £38,000
11 winners: £30,000
10 winners: £22,000
9 winners: £14,000
8 winners: £6,000
7 winners: -£2,000
So for every 1 less winner he has, his profit drops by £8k. His strike rate would almost have to halve before he makes a loss.
Then again maybe he was unlucky to only win 13 of the bets...
