The theoretical longest run of outs one should expect of the Fav ,which statistical show a strike rate of 30% ,
is 20 OUTS in a row, at some time , it might only happen 3 times within a year ,but it will happen , we just dont know when the run will start & end.
So one must have a provision in place to try & gear against total desimation, one idea is to stop once you have 8 outs in a row then start again once one of your selections gets up.
Last start winning Favs. win approx. 35% in their next start.
