backtesting systems for greyhounds... How many races to test?

[sprath]

Hello all, I'm not sure if this is in the right forum or not. I'm new to greyhound racing systems, so I've got what might be an elementary question. How many races do you look at when you are backtesting systems? So far, I've been using a couple of months worth of data to test systems with. Is that too much, too little? Anyone care to share their opinion? Thanks, Steve

Re: backtesting systems for greyhounds... How many races to test? My advice Steve is you need at least 12 months data to test any greyhound system
