That's according to the latency calculations within Ableton's
preferences (as you set the number of bytes in the buffer, it
automatically calculates the latency at your selected sample rate).
So, I am making the assumption that Ableton is not lying to me.
Regardless, it doesn't seem enough to be audibly discernable outside
a "lab" environment.

As you've accurately deduced, I am *not* mixing my direct signal with
the processed signal (other than as an experiment to test latency).
Everything goes into the computer, floats around getting wacky, then
eventually gets output to the PA. If I ran it in parallel to a
direct signal it would limit me a lot more as it would audibly call
attention to what latency there is.
This is especially so in regard to effect routing to external
processors. Every time I run an effect loop to a hardware device,
the latency accretes with every D/A/D conversion (hence, I primarily
use delay-based effects on the hardware side; you're not going to
notice a few extra ms of delay there).
Thus, the overall latency is low enough that I can compensate for it
through my playing, as long as the direct output is not there to
distract/confuse me. That's merely my personal preference, however,
"No more building up; it is time to dissolve..."
