The Plus-Minus stat in Lunacy

I disagree. This year, there aren't even things like penalties, bonuses, multipliers, or autonomous to muck things up. Your score is simply how many balls are in your opponent's trailers, which means it should be fairly easy to calculate in an OPR-like style how many balls your team (on average) puts in your opponent's trailers. The best part is that you can (probably) run the opposite, so you can also find how many balls your team receives in its trailers and have that be a useful statistic to figure out which teams are better at avoiding getting scored on. Assuming that it does work both forwards and backwards, that means you can approximate +/- data this year, which you typically haven't been able to in the past.

Very little beats having people sit in stands tabulating data, but as a proxy (or addition) to scouting, OPR will be quite useful this year.

The stuff that really screws up OPR is exponential scoring or other non-linear scoring styles, because with exponential scoring, you end up with nearly meaningless results. Super cells might throw a small wrench into things, but I don't think they will, seeing as they are essentially equivalent to scoring 7.5 moon rocks.

Anyway, we'll see when the first set of scores comes out if an OPR ranking compares nicely with observed data.
