About the assumptions: the decay multipliers (100% under 5 minutes, down to 25% past 24 hours) are illustrative defaults reflecting widely reported research that inbound conversion drops sharply as response time grows. Your actual decay curve depends on your buyer and channel. Treat the output as directional: the shape of the loss is real even if your exact numbers differ. Related reading: lead response time is metric #1 of the 5 velocity sales metrics.

If the annual number stings, the fix is cheap relative to the loss: response-time SLAs, lead routing rules, and a backup queue. All three are standard deliverables in the playbook the SAILS engagement builds.
