Progression is way too slow

[Chikuhitsu]

For what it’s worth, the first levels are actually faster (in terms of SRS intervals), by the way (that’s been verified at least for the radicals).

@rmizuno

For Levels 1 and 2, the SRS intervals are as follows:
2 hours, 4 hours, 8 hours, 23 hours, 7 days, 14 days, 1 month, (4 months?)
I haven’t tested for the last two intervals (I haven’t gotten that far in my second account yet), but that’s probably right.

After level 2, the intervals change to:
4 hours, 8 hours, 23 hours, 1 day 23 hours, 7 days, 14 days, 1 month, 4 months.

Getting an answer right moves you to the next interval, getting an answer wrong moves you back an interval, and getting wrong multiple times in one session… may move you back more than one, i’m not sure. I know when I fail burn reviews (the 4 month interval) it moves me back

New items unlock after the 4th interval (23 hours for levels 1 and 2).
