A Method for Measuring Guest Response Latency

Method

Define the unit as one guest thread from message receipt to the first substantive human reply. Record the channel, the property, the hour, and the message category before review.

Freeze the observation window and the censoring rule. Threads unanswered at the cutoff remain in the result with their age; do not drop them.

Separate automated acknowledgments from human replies. A template that says we received your message is not a response to the question.

Sample business-hours and after-hours threads. A combined median hides the coverage gap that matters most.

Report the median, the 90th percentile, and the share answered inside the published window. Pair counts with two examples.

Findings

A fast acknowledgment can coexist with a slow answer; measure the human reply, not the auto-reply.

After-hours threads dominate the long tail when coverage is thin.

Censored threads must stay visible or the metric improves as service worsens.

A stable channel definition is required before comparing months.
