Attribution debt compounds fastest before peak
Peak concentrates a year of allocation decisions into a few weeks, all taken on whatever numbers you already have. That is when the debt does its damage.

Peak concentrates a year of allocation decisions into a few weeks, and every one of them is taken on whatever numbers you already have. That is when accumulated attribution debt does most of its damage, and it is also when it is least fixable.
Why the damage concentrates
| Peak condition | Effect on the debt |
|---|---|
| Largest spend of the year | Any misallocation is multiplied |
| Decisions taken fast | No time to question the numbers |
| Reported figures structurally inflated | The debt grows during the window itself |
| No baseline to compare against | Nothing to catch the drift |
The third row is the compounding mechanism. Elevated intent, higher frequency and therefore more overlap, and discount-driven pull-forward counted as new revenue: all three inflate reported returns during peak specifically, which is covered in why the gap widens at peak.
So the window that carries the most spend is also the window where your reporting is furthest from reality.
What can still be done
Three things, all cheap and all impossible afterwards.
Take a baseline read on an ordinary trading month, so the peak read has something to be compared against. A €99 one-time read on a Google Analytics export does it, refundable within 30 days, no questions asked.
Compute your claim ratio now, before the window, so you have the normal-conditions figure. Recomputing it after peak then tells you how much the window inflated it, which is a number worth having.
Freeze channel grouping and lookback in a dated document. Mid-window changes cannot be undone.
What cannot be done now
Starting a geo holdout, which needs a pre-period and weeks of running. And changing measurement method, which makes before and after incomparable at exactly the moment comparability matters most. Dates are in the last day to start a holdout.
The read that pays the debt down
The post-window read, in the two weeks after peak closes. The constraint is your analytics retention setting, which can expire and take the detail with it, as covered in the two-month retention trap.
Diary it now. The full calendar is in Black Friday measurement deadlines.
The honest note
None of this is urgent because a vendor says so. Baselines cannot be taken backwards, retention expires, and mid-window definition changes are permanent. Those three are the only real deadlines, and all three are cheap now and impossible later.

Frequently asked questions
Why does attribution debt matter most during peak?
Because peak carries the largest spend of the year, decisions are taken fastest, and reported figures are structurally inflated by elevated intent, higher frequency and discount-driven pull-forward. The misallocation is multiplied at exactly the worst moment.What can I still do before the window opens?
Take a baseline read on an ordinary month, compute your claim ratio under normal conditions, and freeze your channel grouping and lookback in a dated document. All three are cheap now and impossible afterwards.When should I read peak performance?
In the two weeks after the window closes, provided your analytics retention setting still covers the period.
