Every workstream in the plan carries a stop condition written in advance: a measure, a threshold, a date. When the threshold is missed, the workstream stops. That is a rule, not an end-of-quarter negotiation.
I promise no figure — nobody honest can, too much sits outside both our control. What I do guarantee: you will know at any moment why the budget sits where it sits, and what you would need to see to move it.
One thing is handled in the plan itself rather than after the fact: revenue concentrated on a single channel. A plan that only holds while a platform stays friendly is not a plan, it is a bet — and it settles the same way every time, on a Monday morning, without notice.
