Thanks, I was half expecting troll responses.
I assumed the skip today's reviews addon was a bad addon. It just sounded like a "don't do work" addon. But if it can spread them back out over a number of days I might try that. I've never used any addons that modify when cards are due though. I wonder if I should just do the hard thing and review them all normally.
I really want to get a proper schedule and plan down, to get it back under control, say by the end of the month. If I don't have a plan to stick to, I don't know if I can ever get them down. So the former sounds more tempting, since it would give me a set amount to do each day again. But if I do it once, I could get into the habit of skipping in the future, which seems like a bad habit.
I had something like this happen before, I just made a new deck (the 2016 one) and capped the old decks, never adding new cards to them. Eventually they came down over a period of months. I don't really want to do that again because a lot of the words in 2016 are quite new and I mined them all myself, so it's stuff I do want to know in the near future, but the thought of going through 2500+ cards is so intimidating.
