What Pulse is
A 0-100 score updated nightly. 50 is steady state. Above 50, your identified-guest base is accelerating. Below 50, it is decelerating. It weights frequency and spend equally.
Zones and what to do
70+: don't intervene. Whatever you're doing is working. Document it.
40-70: normal. Use this window for campaign experiments.
Below 40: something broke. Check identity capture rate first (is the team still asking?), then check lapsed-guest count (are you missing the re-engagement window?).
What Pulse is not
It is not revenue. Revenue is in the POS. Pulse is the leading indicator, it moves 2-4 weeks before same-store sales moves. That lead time is the whole point.
