Use the Reorder Script and go through reviews level by level. This allows you 2 things: it allows you to measure your progress in another way other than total number of reviews (ex: yay I finally did all reviews from level 10 to 20 \o/), and it helps controlling the amount of reviews that will come back at you while you’re still murdering the pile.
Nice advice. 
Like you wrote, it is nothing I would be doing in general but makes a lot of sense in this specific case when you don’t want to reset.
I might start doing this for the next few weeks…
