While working on improving the handling of WWV messages
I did some digital archeology and found that the propagation
display (Ctrl-P) is a straight port of MICROMUF.PAS, a MUF/LUF tool
from the 80s. It was originally written in Basic then translated
to Pascal. Here one can still find both:

(replace X with http. I'm unable to post mails with links...)
I suggest to include the original credits to our source.
The Pascal version compiles on a 3.7 MHz Z-80 board in 8 seconds
and drawing the chart takes ~45 seconds. Not that what you'd want
to do during a contest. Those were different days...
For those interested in seeing CP/M and Turbo Pascal 3.01A in action
here is a 2 min screen recording:

At the end I swithed to TLF's Ctrl-P screen with the same settings
for comparison.
This page gives a good review of propagation prediction programs
