I find that three times the day of is adequate for getting the most out of an episode. And then I usually watch it again on Monday before the new one comes out. Yesterday, though, Angela and Melissa and I watched a ton because we needed to get Melissa caught up in time for the finale. Sunday we watched BGC seasons 3, 4, OoM, and the first 2/3 of 5; Monday we watched the rest of 5, Recovery One, Recon, Relocated, and all of Recreation. It was some intense and awesome marathoning.
