The only thing I can say is that I remember having quite a hard time when my buddy used all single letter variables and reading his code, back when we were learning C at uni. Not sure if after a while one can get used to it and have some "buffer memory" (sort of speak) in the brain for allocating single letter variables while reading or working with code (and if I ever had such thing for the time being), but I do remember writing in paper which variable was which when I got lost after 50 lines or so while reading - and helped me to "debug" because, a couple of times, things didn't work as expected because it seemed it was he who mixed vars when writing the code
