Tonight I get hit with this nice little surprise:

Yeaaaaaaahhhh... not really looking forward to tomorrow night.

What's the worst you've seen?

I was up to 500 for a few days after adding about 100 cards/day for a few weeks when doing RtK a couple months ago.

If you include my sentences/vocab/etc I spiked over 900 once! Thankfully it's down to about 80 for RtK and 300 for sentences/vocab/etc.

My RtK number at over 500 might seem like a lot, but I knew how to write over half of the cards I added (and very familiar with the rest), so it's nothing compared to what you're doing...

I was on vacation in Europe for 2 weeks, and was planning on keeping up with my RtK reviews (which didn't work out ^^). Ended up going about 10 days with no reviews and had around 375ish to do. Most I ever did a day.

Other than that, even now, I sometimes skip RtK reviews for 2-4 days at a time because I hate doing them that much, and get stuck with 120-150ish up for review at once.

As for my Anki decks, I've never had more than 75ish due at once, at that was when I suspended the deck for a few days thinking I wasn't gonna do it for a long time >.> I haven't been too motivated to add any new cards to any of my decks the last few months, so my reviews have never been too out of hand.

I think the worst for me was around 550. I try to keep a regular schedule, so for the most part I hang at about 400-450 reviews a day, and there is not a lot of variation.

I find that if I get a large, intimidating number of reviews scheduled, it helps to just take it a little bit at a time instead of in one sitting. Also, sometimes I actually tend to work faster when I have the pressure of a lot of reviews bearing down, so it takes a lot less time than it normally would

The worst I've had was about 200-300 (Kanji only) after having no access to the internet for about a week. Counting all reviews (Kanji, Japanese, Korean, French).. I don't know for sure, but it's been at least 1000.

I have done nearly 2500 in one day before... don't ask, and yes it took all day.

900. During a full day at work. There have been days when I had nothing to do at work and could barely clear 75. I wonder what happened that day?

Also, I once did 300 in one hour. I was actually sweating and my heart was beating fast at the end.

I guess the most reviews i actually did in one day was probably about 400 or so from RTK. I've had like 1000 cards due at one time though, I just never was able to plow through them (and If I had I would probably have had about the same number due during that week). I bascially added about 600 cards in 3 days and then the winter holidays hit. I traveled, went to a wedding, and visited family. When I returned a week later it was at 1000. It literally took me about a month to fully recover from that. That was a horrible horrible month.

900 ish...

If I'm adding new cards I get above 300 reviews every day. It doesn't take long for them to pile up... But hey at least I'm learning something

A few hundred, when I let it build up. I generally never have above 150 unless I've skipped reviews.
