I totally agree that you must keep detailed records of your bets and regularly review them if you want to be successful. This is the only way you can find out where your strengths and weaknesses are - you can then concentrate on improving your weak areas or simply cutting them from your betting system and going with your strengths. For example through my record keeping I identified that my system was losing money on Slow/Heavy tracks so I have simply stopped betting on these conditions until I can work out why.
