Triple Whale model-channel hole is not Northbeam channel coverage
Score missing model channels against spend channels for one Triple Whale pixel window. That score is TW channel-gap %.
Pair: Channel-coverage gap on Traffic. Northbeam twin: channel coverage. Dollar twin: spend coverage.
What you type
Spend channels missing from model — Spend channels present in platform spend but missing from the Triple Whale model in the window.
Spend channels — Spend channels in that same Triple Whale pixel window.
TW channel-gap % = missing model channels ÷ spend channels × 100. Fat TW channel-gap % usually means pixel / mapping lag — chase that path; never invent a TW channel-gap chip.
What not to do
Skip inventing TW channel-gap %. Skip dumping a Northbeam or Rockerbox channel file into Triple Whale fields. Skip folding spend-$ coverage into channel counts. Skip blending brands when one pixel owns the hole.

FAQ
- Is this Northbeam channel-coverage gap?
- Different attribution book. [Channel-coverage gap](/manuals/northbeam-channel-coverage-gap) reads Northbeam. Here you only score Triple Whale missing model channels against spend channels.
- Is this Triple Whale spend coverage gap?
- Sibling Triple Whale door on dollars, not channels. [Spend coverage gap](/manuals/triple-whale-spend-coverage-gap) is tracked vs platform spend $. This page is missing model channels ÷ spend channels.
- What TW channel-gap % should I invent?
- None. Pull missing model channels and spend channels from the same Triple Whale pixel window.
