Notes

Into lactater: one row per stage with intensity, lactate and, if recorded, heart_rate and rpe; the resting sample is the row with intensity 0 (the CSV template that comes with this sheet has these columns). A last stage that was not completed goes in at its time-weighted intensity: the last completed stage plus the increment × the seconds done / the seconds of a full stage, or is left out with max_intensity. Recovery samples go in recovery, as minutes and lactate, with stage_duration.
