Spellcheckers aren't smart enough, should read:

Hahaha... guess you need a complex conjugation checker. Owen, I was
assuming no feedline and an antenna tuner at the feedpoint and being
very gracious towards that antenna tuner's abilities ( I wouldn't be
surprised if a tuner could match 11-j750 with 1.5dB of loss, though
maybe not a 100W-class autotuner).

As far as the transmission line calculator goes, I use it ALL the time.
It's a fantastic resource, both technically and ... well,
rhetorically. A lot of folks will say their antenna works even if their
antenna is a 40 foot dipole fed with 50 feet of RG-58 on 40m.

They can hear people with it, their rig's autotuner loads it up just
fine on 40m, and they can "make contacts" but their effective radiated
power is going to be 1.6 watts... and feedline loss is an
environmentally-unfriendly way to be a QRP operator.
