Scoring based on wave gun start, with no waves pre-assigned.
The StartRead result is used to pick the first chip read of a participant as their start read.
The timer collects a marker with each wave start. The StartMarker result selects the last marker before StartRead.
Finally, the FinishRead result takes the first read after the StartRead plus a certain offset.
With these three results calculated, one can then calculate gun and chip time.
