speed-focus-mode VS anki-delay-siblings

I'm using Anki for language learning and a while back I thought about decreasing the amount of time I spend on a card with the add-on Speed Focus Mode. My idea was by decreasing the time spent per card, I'd go through more cards in the same amount of time. I went from 30s per card to 12s for front AND back).

Speed Focus Mode: Auto answer to save time.

I use this one: https://ankiweb.net/shared/info/1046608507

I don't usually actively search for gamification add-ons for Anki, but I think some extensions I use currently express some aspect of gamification: 1. Review Heatmap visually shows the amount of days where you reviewed & didn't review Anki. It serves as a progress bar and motivator to continue to do daily reviews. However, I don't know how long you plan to run your experiment for: if it's only for a few days then it may not be a very strong motivator. 2. Speed Focus Mode caps the amount of time you can spend recalling a card to a user-specified amount, and auto-flips the card after the time limit. This add-on significantly changes the way that I review Anki. When using this add-on, I find myself being more willing to accept that I forgot something, as I'm motivated by the timer to just put out an answer by the time limit, even if said answer is wrong. When using this addon, you may have challenges knowing what time limit to set on the cards, however, depending on how complex the cards are. I usually have to spend much more time on my japanese cards than english vocabulary cards, for example, to recall something.

"Speed Focus Mode" add-on may help you about that :)

Is there an add-on (like Speed Focus Mode (https://ankiweb.net/shared/info/1046608507)) that allows me to see my 'card creating speed'? I want something that can signal me that I am creating enough cards in a given interval of time.

Instead of messing around with ease factors, I'd suggest the Suspend siblings until mature add-on for new cards, and Delay siblings to spread out the current ones. That should pretty directly get what you actually want, with your siblings introduced at different points.

Once they're all in a single note, then I do more-or-less the opposite of your approach, by pushing the siblings as far apart as possible. I use Delay siblings for mature cards, and Push Paradox for new cards, although I'm strongly considering moving to the newer and maintained Suspend siblings until mature add-on.

Because they're all siblings, I can use Delay Siblings and Suspend siblings until mature to spread them out, so they don't hit all at once.

You can't make cards from separate notes treated as siblings. What you can do, though, is generate several cards from the same note. For instance, I modified my Basic note type to have 10 pairs of Front and Back (Front 2, Back 2, Front 3, Back 3, etc), and an Extra field to put on the backs of all the cards. That way, I can put a bunch of questions together in a single note and generate separate cards for them. Sibling burying, the Delay Siblings add-on, and the Push Paradox add-on help me spread them out further.

Rescheduling siblings like this addon does should be a built-in feature. Without this you can get a yard with a multiple-year interval, and then get the reverse card the next day. This doesn't accurately capture if you've learned this card because your memory was just refreshed the day before.

Why doesn't anki make something like this add-on a standard feature? https://ankiweb.net/shared/info/1369579727

Some cards contain information that can be found in others without necessarily being siblings. I want two separate cards to become siblings so that I can automatically delay one of them, by using an addon like this one. This would fix the problem of reviewing card A and then later in the same study session guessing another card B correctly just because card A contained related information.

Sorry if I'm being annoying, but there's one more thing - take a look at this add-on and see if it's compatible with FSRS.
