have faith, from here your overall handicapping looks sound.
With my Horse Betting I use a progressive stake and had a run of 5 outs until the last 2 bets today at $1.95 (happy to end the outs) then the big one at $7.50. Just stick to your guns.
I also use a similar Staking PLan on my Sportsbetting. Was on a run of 6 in a row until the current match, the only reason I backed it was I was at the start of the cycle. (stupid really)
