Enable this to see wave count alternatives in the Alternate Wave Counts gadget when counting subwaves of a particular larger timeframe wave. If this option is enabled, you will be able to choose between various alternate wave counts for the current chart in the Alternate Wave Counts gadget, just as you can with full/complete wave counts.
HINT: If you don’t find the subwave counts you’re looking for, try to delete all waves forward from the wave in question and count subwaves forward again.
