Don't confuse deck tempo and global intervals
Vocabulary Deck Settings
Two screws: in the deck, the pace between cards; in the app settings, SRS, daily goal, and session limit. If you lump both together, you won’t understand the app and will end up complaining about the wrong thing.
A maintenance deck can be slower than an A1 daily routine. The 1-3-7-30-90 intervals should still be kept together; otherwise, every deck becomes a cult.
The session limit protects against “Sunday heroism.” I set it to a number I can actually reach on Thursdays, too.
Settings often save automatically. Still, after making a change, check one card to see if it feels different.
