Yes, it does.  It's internally fixed at 750 for the Federal and 850
for the California stabilizer units.  If the engine (and hence the
distributor pulses) slows below that figure the unit artificially
advances the pulses that it passes on to the ignition unit.  You can
watch it happening, just put a timing light on a 1.9l that has the
idle stab connected and switch on some electrical loads.
