You're totally right. It is plain wrong because it tries to use windowed reduction in APL like infix in J. An easy fix would be to combine  with concatenation   by atop so that it looks like   (or   in Dyalog 18.0); a general solution (allowing window size higher than 2) would be to extract windows and apply average on each of them. I doubt if it's worth keeping either way in this context. --Bubbler (talk) 14:07, 27 June 2020 (UTC)
