The primary concern is that most video review overturns would result in replaying matches, and thus the added schedule risk. It's not fair to penalize alliances for their strategic behavior based on the score/field conditions that are presented to them in real time, and then go back and adjust those via video review. For instance, if a team crosses a defense 3 or 4 times to damage it, they can't get the extra time they wasted crossing that defense back. Or if a team makes a call to ensure a capture at ~15seconds rather than scoring an extra couple balls based on their real time scoring, then have that scoring adjusted when you give the other alliance a breach that didn't exist previously. Virtually any case where errors are found in video review should mandate a replayed match. Thus the schedule concern.

As a coach, I'm happy to agree with this frustration. But we've gone years without this being true in real-time scoring, since as a referee it's completely normal to correct these things in non-video reviews before posting final score. It's annoying, but it's been part of the game since the advent of real-time scoring under T20 (identical to T15 last year). As long as it's clear when there will/won't be a replay, it's up to coaches to take it in our strategy.

Re: Video Review Needs to Happen Now

Blake, there's one other data point that I think could be useful in that analysis:

# of matches where video replay was available for use. That is, how many matches at the event in question could have possibly had a review? (Basically, how many matches did the event play? Unless, of course, it's elims-restricted, in which case it's how many elims matches were played.)

And the reason that that particular data point could be useful is that it will give a broad-spectrum picture of how used video replay could be, if available. Just as an example, if in 5 offseason events (that offer replay review) each with 50 matches replay is used 5 times and the call on the field is overturned* once, then you could say that there's a 2% use rate and when used, there's a 20% overturn rate--but overall, the overturn rate is 0.4% because only one call was overturned.

That sort of data can be used to figure out timing of events (and what the limits for review are) and ref performance. Both those numbers could be pretty important, the latter feeding into better ref crews if need be.

*Change of any sort to the result of the match--points, winner, you get the idea.

I'd suggest that "control" events track number of scoring changes (team or field staff initiated), and number of (denied, obviously) requests for review.
