i use dons ratings straight from winning more but only the class figures from his tables of different states, i make my ratings based on the results of major meetings and apply the most recent performance to any race i am handicapping.
i work out the rating for each runner in an event but bet on the first 3 rated horses paying $10 or greater on the tote, in this way i get maximum overlays. as for the staking plan l want to protect the details involved but it involves a moderate progression plan which wins overtime, its necessary not to be too aggressive. i restart the progression each time i make a profit.
