While watching ISR #1, I realized that often, notes scored towards the end of the Amplification period were consistently being awarded 2 points rather than 5, even when being counted within the three-second grace period as specified in 6.3.3:
For example, in Match 4 of the playoffs, A6 (Blue) amplifies with 43 seconds remaining in the match, and 32 points.
With about 3 seconds remaining in amplification, 6740 and 5654 both score a note in the speaker. However, these notes aren’t processed at the end of the nominal amp period, meaning the score is still 32.
Immediately after amplification ends at 0:33, the first note is counted for 2 points, rather than 5, despite clearly being within the 3-second period. (The same happens for the second note, which is scored at 0:32)
This happened more than once throughout the event. Another example is Qualification 13:
The Blue alliance amplifies at 1:06, with 51 points
9738 scores a note in the speaker with 3 seconds remaining in amplification, and this note is still unprocessed as the 10-second period expires.
Immediately after amplification ends, the note is counted for 2 points, despite clearly being within the 3-second period.
While neither of these issues directly impacted the outcome of a match, I can easily imagine close matches being significantly impacted by the 3-point deficit resulting here.
