Load a STATSports export
Export the session from Sonra as CSV with all metrics (the standard "All Metrics" export). Drop it below. Everything runs in your browser; the file is not uploaded anywhere.
Drills in this session
Tick drills to merge them into one (summed distances and efforts, peak max speed, mean m/min). Mark which drill is the full session so the report can show active time versus total time. Excluded drills are left out of the session aggregate.
Session aggregate
A "Complete session minus breaks" row is built for each player from every drill that is not excluded and is not the full-session drill. Durations come from drill start and end times.
Squad profile
Assign a position and position group to each player so benchmarks and charts can compare like with like. Override a player's max speed if the Sonra value is stale. The profile is saved in this browser and reused next time these names appear. Export it to keep a copy or move it to another machine.
