I've tried both 5 short workdays and 3 longer workdays. I like 3 longer workdays better. A full day for work and a full day for something else mean, to me, that I can focus more fully on work and then focus more fully on something else. A "half work, half not work" day means, to me, that I can't quite focus on either. TFA presents the shorter week [the alternative to a shorter day] as 3 consecutive days; I prefer interleaving work and non-work days, so as to neither be absent from work for 2 days in a row, nor work for 2 days in a row.
