qjackctl is not estimating but calculating the nominal round-trip latency:
latency = (period size) * (number of periods per cycle) / (sample rate)
This nominal latency is the ideal case. Usually the total latency is
larger. With generic hardware the only way to learn about the total
round-trip latency is to measure it. Ardour - since version 3.5 - has a
built-in tool to do so.
Some general information (predating 3.5) can be found at
