Let's engage with this.
If we ignore the time it takes to scramble, look, plan, basically if we only consider the time it takes to do DR. Scrambling, thinking, doing EO, and finishing the solve, as well as writing your thoughts down, all take 0 seconds.
You're only doing DR.
A decent FMCer can find a worthwhile DR after an EO in like 5-10 minutes. Scramble dependant. Let's call it down the middle and say 8 minutes.
8 minutes per DR, 60 EOs, 10 DRs each.
Unfortunately, with 60 minutes to find your solution. You can only get 7-8 DRs done in total. Which is a bad thing for this idea, as 7 is noticeably smaller than 600.
So let's add a new variable.
Assume every solver is permitted a line of cocaine before their attempt.
I would like to imagine the amount of found DRs would jump up to around 12-15. Enough to finish 1 EO, and maybe get halfway on a second. Unfortunately, we are still very short of the 60 EOs target. If we're pessimistic about it, and say that the artificially locked in solver gets 12 DRs, then we'd only be 1/50th of the way through the 600 DRs total.
In short, this idea would be good if attempts lasted 50 hours and FMCers had a doping scandal and you didn't need to scramble or think or solve eo or finish the solve after DR or sleep or eat.
