My 19th edition of the ARRL Antenna Book treats additional power
loss
due to SWR on page 24-10.

Best regards, Richard Harrison, KB5WZI

========================================

On this subject the only hope of discovering the exact loss on a line
with SWR is to do an exact complex mathematical analyis for yourseslf
and hope you don't make any mistakes.

For starters, the calculated curves shown in ARRL publications over
the years, as plagiarised by the RSGB, are in error. But they are near
enough not to lose any sleep about.

Why the importance attatched to this line feature I can't imagine.
