Personally, I keep Ghosts on the default (full) setting, and I use them as a gauge to remind me to slow down when I’m going too fast.
As for getting rid of 336 ghosts: While it might appear that that would be hard to overcome, actually it really is not. Remember that ghosts only go up to SRS stage 4, and then they are slain.
The ghost stage timings are a little different than for regular reviews. They are: 4, 12, 24, 48 hours. So, if you get all of them correct (and do them immediately), that’s technically only 88 hours, which is less than 96 hours, which is 4 days.
Thus, ‘in theory’, you could get rid of all of your ghosts in just 4 days.
Of course, that’s not likely to actually happen, since they are ghosts for a reason – you got them wrong at least once before. But I would recommend thinking of ghosts as very ‘lightweight’ reviews. They don’t hang around in your review queue for ages and ages like regular leeches do.
So, surefire way to get rid of those ghosts without resorting to a Reset or changing ghosts to ‘minimal’:
- Stop doing any new lessons until you get your ghosts back down to a reasonable level. Depending on your preferences, probably fewer than 20 ghosts at a time is a pretty good starting level.
- Just continue to do your reviews as usual, until a) you start getting regular reviews correct so often that they no longer generate (very many) new ghosts, and b) you steadily, one after another, slay those ghosts by taking them seriously – if there are any that you keep getting wrong, then do some extra study/reading until you figure out how to answer them correctly.
In roughly a week or so, your current ghosts should dramatically decrease.
Only start doing new lessons after you’ve got your current review stack and ghost stack back under control.
I guess the key POV that I adopt when thinking about ghosts is that: Ghosts are opportunities to really polish up on grammar points that have been tricky in the past. I don’t see them as obstacles. Again, I use them to signal to myself that I need to slow down on my new lessons, until I can get my ghosts back down to a reasonable level.
