A related question: What sort of time per card have long-term Anki users experienced?

As a first "project" with Anki, I've been learning english vocabulary. Half are new words, and half are words I recognized but understood only vaguely. I have 2300 cards, and spent around 18 hours reviewing and 8 hours collating cards, which is around 40 seconds per card. Three months out, I'm reviewing ~30 cards a day in ~2 minutes.

I feel like a fool when I think that I've spent 26 hours studying vocabulary this summer, but I'm pretty pleased with the equivalent "40 seconds to learn a new word". More generally, the cumulative time spent on any habit will sound pyschotic when quoted over long time periods: 4 minutes a day is 24 hours over a year.
