I believe that if I have an advantage, then the more bets I place, the more money I turnover, hence the more money I make.
On the other hand, if I don't have an advantage, then I would prefer to get it over with as quickly as possible so I could move on to my next venture. Which hopefully will never happen.

I also find that my selections win and lose in runs. I seem to have more days where I win a considerable amount or lose a considerable amount as opposed to breaking even. Either a good or bad day...
Therefore by quitting early on a winning day, I would think that I am prematurely cutting my run short.

Probably just a pschological thing. I don't like missing races whilst my bet is above the base. But I also know that regardless of the races I miss out on, they will even out as good days and bad days.
I am not the kind of person that if I happen to miss a race or a day, to check the results to see what might have been. I prefer to think that if I didn't bet on a race, then it never really happened. (Just like after a night out, if I don't remember doing something, then it never really happened.... )...

I only bet on races that BF has a market on, and at this stage have limited myself to Australian gallops races... So that is my 30-40 races per day.

Because I use such a non aggressive staking system, it takes a long time to recoup my losses. Therefore I see a day as more a short series of races as opposed to a start and end. It might take my system 3 months to get back to base, therefore I will never stop my day short when I am in front.
