Crash-Free Session Metrics

A more useful stability metric than raw crash count could be:

Crash-Free Sessions

Percentage of gameplay sessions completed without a crash

This could be segmented by:

Platform

Hardware

Map

Mode

Driver

Game version

Session duration

Example

Build A:

Crash-free sessions: 99.4%

Build B:

Crash-free sessions: 98.7%

Even if average FPS improved, the regression should immediately be investigated.
