Your question

What do you want to understand?Which result matters?

CHECK 1 / 3

Define the proposed edge

Specify the channel slice, current spend, proposed reduction and business outcome to protect.

Check your interpretation. The removable portion is a hypothesis; high average ROAS or a flat fitted curve does not establish it.

Which spend step and acceptable outcome change are you considering?Where are you with this check?

If you cannot resolve this check

Do not choose a percentage simply because it is a convenient round number.

CHECK 2 / 3

Plan the comparison and delay

Choose assignment or a defensible control, the observation horizon and checks for spillovers into other channels.

Check your interpretation. Account for delayed conversion, seasonality and demand changes. A before/after comparison alone may mislead.

What comparison would distinguish a spend effect from normal fluctuation?Where are you with this check?

If you cannot resolve this check

If expected loss is smaller than measurement uncertainty, redesign the test or extend the evidence window.

CHECK 3 / 3

Set the checkpoint before launch

Record who can change the budget, the downside limit, restore condition and how ambiguous results will be handled.

Check your interpretation. A test plan is not an instruction to change a live campaign.

What evidence would support keeping, restoring or revisiting the lower spend?Where are you with this check?

If you cannot resolve this check

Get a review when revenue risk or interference makes the first step hard to reverse.

What would help you move forward?

You can continue with partial observations. Recording a check does not verify its conclusion.
