"This way, my output power measurement is taken
AFTER the majority of transmission line and ATU
losses, probably giving me at least a 15% power
advantage over locating the measuring point right
at the main transmitter box.

Your "15% power advantage" amounts to a ~ +0.6 dB
increase. An "S unit" is generally accepted to be
6 dB. Not much of a gain.
The 90% to 105% limits from licensed TPO, common
point power or antenna base power set for
broadcasting amount to about -0.5 dB to +0.2 dB,
respectively. Again, not a real big change on the
receive end.
