Only if the antenna is near resonance. Otherwise the tuner should be
pretuned with an antenna analyzer or noise bridge or tuner tuner (fixed
Z noise bridge. The rig and linear used with that tuner should be tuned
into a dummy load and all that tuning can be facilitated by keeping a
tuning chart with good logging dials on the adjustable components.

I find peaking receive through the tuner speeds adjustments when I've
neglected to look at my tuning chart.

For sure, but when the only tuning instrument is a SWR bridge that runs
at full transmitter power, tuning on the air will be done.
