? Gave small treat before stalling

My boy just started Prozinc about a week ago but his numbers have mostly hovered in the 118 - 175 range so a lot of shots have been skipped and when he does get shots they have been 0.25u or slighly less. His low has been 111 and I would like to see him dip into the greens so I started shooting in the 175-200 range and am tempted to shoot a little lower. This morning he was 152 and before I remembered the stalling tactic, I gave him the tiniest bit of a churu treat (maybe the size of a dime). Should I just skip the shot again? Will the churu treat cause a food spike in 20-30 minutes?

 

NVM. As it turns out he dropped to 136 after the 20-minute stall so I guess the treat was irrelevant.
