I will say that it wasn't the normal method I would use on CSE. I'm partial to something much closer to the strategy you mentioned, but with the difference of clearing all the gennies and then doing the cubes one by one. In this particular instance I was reacting to the behavior of the rest of the team. MRRML does seem to be the most agreed upon strategy for a quick and efficient victory.
I still find that a great majority of PUGs are successful runs ending with a victory. The only times I get frustrated are with people spamming the team chat with rage about other players.
If I find myself playing when you're on I'd love to run some STFs with you (or other fleetmates). I've actually never done the ground ones, and am just getting some Mark XI ground equipment with EDCs from the space STFs so I no longer need to remodulate manually.
