Ugh, I didn’t constrain the problem statement enough. I’ve no desire to chuck the item into the bowels of the review queue, and fundamentally change the WK algorithms. I merely don’t want it next, or second, etc, pick your preferred minimum distance. Positioning it later in the batch of items currently being reviewed would suffice.
When I fail an item, it is because I couldn’t recall outright or reestablish the mnemonic connection. I then read the full mnemonic over again, multiple times, trying to identify and correct the mistake I made. If I am immediately quizzed afterward, this is testing my reading comprehension and active working memory, something I already do myself in studying the item. I have no problems here, and always get it 100%. If however, I put some different items in between, and overwrite my working memory with something new, I feel the recall takes more effort, effectively going further back than my active working memory. How far? I don’t know. My speculation is a more beneficial distance.
Guess I’ll start poking around in the JS, and see whether something like this is even possible.
