I like your Hot form Class droppers and am looking forward to playing that method when the flat starts. Perhaps we can add one or two filters to improve the strike rate even more.
One of the aspects that we both have slightly ignored from the Peter May article, is he suggests looking at races with a maximum of 10 runners. I have decided on races with a maximum of 12 on the A/W at the moment, but that is an area that would cull some of the races for you to study if you did restrict to that sort of number.
My idea with the one point a day is now it seems to be working nicely, I can compound the stake if I want to as mentioned by Maverick and others on here.
All the best.
