The basic cause-effect of this, as an example, is that even if the minibot moves the plate 1", causing the sensor to be in contact for 3/4" of that movement, the contact time of the sensor is much less than the 100ms I listed. So we need either a higher sampling rate to allow finer granularity in the false-positive algorithm, or we need a dampening mechanism that's implemented by the "GDC" or by teams.

As far as I can tell, interrupt-driven signals have just as much probability for false-positives as sampling does in this setup. The interrupt would have to be held high/low for a certain amount of time to ensure it's a valid trigger, which still requires some sort of 'time' specification for teams to ensure they don't lose contact with the sensor too quickly.
