First move is probably setting your guardrails, you're not going to hold an exact number, so at what range does adjusting make sense? At least a couple pounds either direction, depending how much your weight naturally swings.
Drop below that range, eat more, go above it, eat less. In this situation appetite control mostly tracks with dose size.
What's your trend looked like on the current amount over recent weeks? That'll hint at how big an adjustment you need.
Then pick whichever's simpler for you. Personally I'd rather dose the same weekday every time instead of tracking a rolling ten-day cycle. There's an app that could handle that, but not really my style. For me, going smaller per dose, maybe shifting from twice weekly down to once, feels more manageable.
