Sorry if this sounds completely stupid, but i am just starting out. I do my regular form analysis each week based on all majour factors formline, barrier (you know the rest). I was just wondering how you guys convert this information to establish price ratings such as those expressed in the ratings challenge? For example if i find a horse that i this is the winner, how do i rate this horse at a price? Furthermore, once i do rate say my top 4 runners at prices i assume that if my prices are below those given by TAB or bookmakers that i back the horse?　Any help would be greatly appreciated. Thanks.
