I experience my BLD jumps when I spend a day or two doing other events.
i've done a few BLD solves before, and i would say BLD could be a little more extreme in this case since it takes so much more brain power than non-BLD, and recovering from mental fatigue can take a while. 3x3 isn't really physically or mentally tiring at all.
like maybe as you improve during your solves throughout a few days, your brain gets weaker, making your times slower even though you have gotten better. a few days later when your brain is back up to speed, your times improve.
