Good observation CP!
The end of year result is the most important but also you have to have at least over 40 bets a month (betting on met. races only).
You also have to break down your betting results at least into monthly chunks, you have a much better understanding then, of how you are traveling.
No use getting all your profit in one month, even if the year was in the black!
I am treading water in Feb. would go backwards in March, (if I persisted with my main handicapping-rating)
Sept. and Oct. are the most profitable, and I'd loved to know, why, two month would be bad, two excellent, and the rest just good?
Cheers
