Hi Topsy,
I agree with you it is usually the human
element that lets down.
As I posted a while ago I had a system using the martingale(Build up)staking plan.
My son used it for two years and never went bust,lots of hairy times of course,BUT the point Im making is If I had not been with him he would have lost his nerve many times and come out losing.
This system ran from meeting to meeting and never ended.
The classic example was Randwick one day and he was on I think about his 8th bet from the previous meeting.I still remember the horses name BRAVERY,5/1 prepost first starter.80/1 with the books.
He just didnt want to back it. I made him do it telling him the horse doesnt know his price and whoever did the prepost thought it was a 5/1 shot.
Old story last on the bend won by a length going away.
If what you are doing has some reasonable basis stick to it.
It is ALWAYS the human element that lets down.
Cheers
