One way to look at it is this: a perfect score in autonomous (assuming you score with all 5 pre-load and don't somehow get some batons from the opposing alliance) would be 502 points (2 x (47*3 + 25*2)) for the rolling goal baton scoring, plus 2*45 for batons dispensed, plus 2 x 15 for balancing). Assuming you don't dump out any batons during driver-controlled, you would get another 382 for the rolling goal baton scoring, for a match total of 884 points attributable to a perfect autonomous game.

But if the middle dispenser is blocked and impossible to get to in autonomous, you could get only 239 for an otherwise perfect autonomous game (33*3 + 25*2 for rolling goal baton scoring {assuming no magnet batons were in the middle dispenser}, plus 2*30 for batons dispensed, plus 2 x 15 for balancing). With an additional 191 added for rolling goal baton scoring in driver-controlled (assuming you get and score all the batons during driver-controlled that were blocked during autonomous), your match total would be 430 (attributable to autonomous plus the 14 more batons from driver controlled).

Thus, against the theoretical "perfect" opponent, blocking the middle dispenser during autonomous alone would cut the opponent score by at least 263 points in autonomous and by at least 454 for the game as a whole (more if a magnet baton or two were in the middle dispenser). Anything that prevents 454 points or more sounds like a good way of preventing at least some scoring.

Probably no opponent will be good enough to approach these scores, but the better your opponents, the more it looks like blocking the middle dispenser might be good strategy (as long as your alliance partner is good too).
I'd like to take an opportunity to say "never say never"
Last year with HotShot we saw some ridiculously high scores and made a few of them ourselves. It's possible you could end up with a situation like that. and for intents and purposes I think all teams should at least have a autonomous that could accomplish blocking the goal.

Now I'm not encouraging a boring defense autonomous mode either. YOU HAVE 40 SECONDS. Please use that time and don't just sit there.
