These results are mirrored from Momentum, not timed by our own boxes. Completeness here measures how much of Momentum's data we hold, so a gap is a crossing we have not pulled or one Momentum itself is missing, not a verdict on timing hardware.

A mat's catch rate is how many athletes it read out of how many we can prove passed it (anyone read at a later split, plus every finisher). A miss only counts when a later split proves the athlete was there, so this is a floor on real losses, never an overstatement.

A box was on site but never hit Momentum?

Add it by hand. Name the mat it sat just before, and everyone proven past that mat counts as a crossing this box should have caught. It is charged as a silent box, not excluded.
