i just spam dropped. youll get the same tt returns if you spam drop or space out. the only thing that spacing out might do is give better avg mu% but i never noticed a difference. spam dropping for 25-45 minutes (depending your excavating speed) then going back and picking up all claims after...
ill throw in a couple pecs here.
this is my small cycle (2-3 hours a day on avg of mining over the last 2.5ish months (September 1st-November 13th)
