If you used jack_iodelay, it would do the math for you

much extra latency is bing caused by the hardware (rather than the period

jack_delay will do this as well, use the -E option.
jack_delay 0.4.0

Measure round trip latency of a soundcard.
Usage: jack_delay <options>
Options:
-h Display this text
-O <playback port> Connect output to named port.
-I <capture port> Connect input to named port.
-E Report excess latency, requires both -I and -O.
The excess latency is the measured value minus the
expected value for the given ports including any
corrections set by Jack's -I and -O options.
