How the Lead Nurture Decision System gate works
How the Lead Nurture Decision System scores 6 buying-readiness levers to 100: a stale-engagement gate holds a high-fit lead at KEEP NURTURING when engagement recency has gone cold, regardless of score — which is how the sample scores 77, clearing the ADVANCE band, and still reads KEEP NURTURING.
How the gate works
This tool grades one lead's fit and readiness to advance to a human. Each control is marked from your own evidence and weighted into a 0–100 score — and then the score is run past a gate that can only make the verdict worse.
The 6 weighted controls
| Signal | Weight |
|---|---|
| ICP fit | 22 |
| Need / pain signal | 20 |
| Engagement recency | 20 |
| Engagement depth | 16 |
| Authority / buying role | 12 |
| Timing / readiness | 10 |
| Total | 100 |
The verdict bands
A raw score that clears ADVANCE (70+) is held at KEEP NURTURING instead when engagement recency scores 0 or 1 - a high fit score with no recent engagement isn't sales-ready.
In the worked sample it scores 77 out of 100 and still reads KEEP NURTURING — This lead's fit score is 77 - comfortably past the ADVANCE line of 70 - on strong ICP fit, pain signal, authority, and timing. But engagement recency is 0: no recent open, click, or reply. A high fit score with no recent engagement isn't sales-ready, so the stale-engagement gate holds it at KEEP NURTURING instead of a sales handoff. The one thing to fix first: Engagement recency - re-engage this lead before it's worth routing to a human; every other lever is already strong..
Common questions
Can something score well on the How the Lead Nurture Decision gate works and still fail?
Yes. The weighted score is run past a worsen-only gate — the Stale-engagement — that can only make the verdict worse. In the worked sample it scores 77 out of 100 and still reads KEEP NURTURING, because this lead's fit score is 77 - comfortably past the ADVANCE line of 70 - on strong ICP fit, pain signal, authority, and timing. But engagement recency is 0: no recent open, click, or reply. A high fit score with no recent engagement isn't sales-ready, so the stale-engagement gate holds it at KEEP NURTURING instead of a sales handoff.
What is a worsen-only gate?
A dispositive rule that can only lower a verdict, never raise it. One fatal flaw overrides an otherwise-good score, because a single disqualifying gap shouldn't hide behind a high average. The tool also names the one thing to fix first — here, "Engagement recency - re-engage this lead before it's worth routing to a human; every other lever is already strong.".
The kit reads and scores - it does not send. Every number derives from the levers you set.
