Eh, i think i'd prefer 4-3 more than 5-3. For the same reason that i'd rather not work 60 days straight and take an extended period off.

As it is, lately i've been working longer chunks of days in a row, 14+ days without breaks and it drains me. It feels like each day after the next really compounds.

It's also why i dislike longer vacations. I get super antsy after day 3 or 4.
