I wrote a simulation a long time ago to simulate workload and time-to-completion for various scenarios, including changing when and how often you do reviews, and what your accuracy is at each SRS level:
You can adjust the parameters in the bottom-left panel:
var accuracy = [80.0, 80.0, 85.0, 90.0, 95.0, 95.0, 99.0, 96.0, 97.0];
var review_times = ['07:00', '21:00'];
For example, the above settings mean the you want to do reviews at 7am and 9pm daily, and your accuracy is 80% on Apprentice 1 & 2 items, 85% on Apprentice 3, 90% on Apprentice4, etc…
I left several alternate settings in the script for reference:
//var accuracy = [90.0, 90.0, 90.0, 90.0, 90.0, 90.0, 90.0, 90.0, 90.0];
//var accuracy = [100.0, 100.0, 100.0, 100.0, 100.0, 100.0, 100.0,
//var review_times = ['06:00', '12:00', '17:00', '21:00'];
//var review_times = ['21:00'];
You can try each the alternatives by removing the //, but make sure only one ‘accuracy’ and one ‘review_times’ line are active at the same time.
You don’t have to stick to the given alternatives. You can manually edit any of the lines, as long as you keep the form correct.
After you ajust your settings, click the Run button in the top-left.
