I use to be the same...had lots of variables took ages to work out a race....sometimes i came up with ripper prices but at what time cost....i started to think what are the main form factors to me the lasr 3 beaten margins are the first thing i look at...if you take the top 6 horses according to beaten margins and put them in order of lowest price to highest price you can find some good exotics then i like to add the class factor looking at what races they have been in lately and giveing them a value.....just with these 2 bits of info you can have a lot of fun
