And so the computer had a moving-needle efficiency

rate of instruction execution by the rate of drum rotation (since there
was a timing track on the drum anyway). 100% efficiency was attainable
but only by simple programs such as a parity check of the drum.
I bet Mel could do it!
(Yeah, I'm sure we all know this link, but here it is anyway,
just in case.)
