I think I know who you’re referring to, and if it’s the person I’m thinking of (user name ‘alygator’, I believe), then the reason they are currently at level 10 is that they had previously gotten to level 21, but ended up taking a 9 month break, found they were forgetting a bunch of items, and thus reset down to level 7 (and already back up to level 9 or 10).
The idea of ‘unburning’ level 1 items comes from the general idea of ‘reviewing burnt items’, but specifically in the context of, “Well, I could have reset all the way down to level 1, and I’d kinda like to review all those items, but I don’t want to do a hard reset all the way back and lose my progress on levels 2 through 7 (and now 8 and 9)”.
So, this is a user who’s specifically reviewing old items, in a similar way to someone who would have done a full reset back to level 1 on WK. This is not a typical WK user, led astray by WK’s system; it’s someone intentionally working around the WK system to have their cake (do a ‘reset’ of early levels) and eat it too (without losing all progress, as hard-resets do on WK).
Some people reset all the way back to level 1, for a variety of different reasons. This is the same as that, except it’s working around the negative side-effects of doing a hard-reset.
For context, I’ve done this method of doing a ‘soft-reset’ (I call it a ‘rolling reset’) for quite a while now, and I’ve thus re-reviewed everything from levels 1 through 26 to the point where I’ve already re-burned most items on levels 1 through 20.
For levels 1 through 18, I’ve re-burned all but 354 out of 3074 total items. In other words, I only have about 11% of items not-yet-re-burned from levels 1-18; i.e. I’ve already re-burned about 89% of levels 1-18.
All this was done while still progressing steadily along the WK track, and I’m currently on level 37. I just sprinkled in ‘unburns’ along the way, and I’ve been doing that for approx. 2 years now. (I go into depth explaining why I did this in the main comment where I posted about this idea in October of 2022: Rolling Reset )
Just saying that it’s not a crazy idea, though it’s definitely not for everyone (or even most people!). It’s just a specific way of accomplishing a specific goal.
Indeed, rather than making me want to give up, it has actually helped me to maintain motivation and keep a nice moderate, steady pace, to the point of enjoying re-reviewing these ‘old friends’ as I continue to progress meeting ‘new friends’.
