I guess I should do some experimenting in SIMH to see what the paper-tape BASIC
interpreters like to digest; assuming I can find the appropriate interpreter images, that
is. I'll include at least an option to include DELs after each line in my envisioned
future tape puncher/reader utility.

You must have had a 33 ASR that returned its carriage within one character time plus
whatever overhead your PET's bit-banging routines had. I think that could vary from
machine to machine based on the strength of the carriage spring, how gunky the carriage
rails and rollers are, the dashpot setting, the ambient temperature, and so forth. Three
character periods (LF-DEL-DEL) would probably work for all but the most grungy machines.
