Frequency change step larger than selected on relatively slow tuning

Running Maestro at 2.4.9 with 6500, connected via gigabit ethernet.  I operate mostly CW and run with a step size of 10 Hz, tuning with the Maestro main tuning knob.  When tuning relatively slowly across a CW signal, the frequency is clearly changing in steps larger than 10 Hz (sounds like at least 100 Hz).  It's possible to not experience the larger steps, provided I turn the knob extremely slowly.  Obviously there's an acceleration factor involved so that if one spins the knob, the frequency will change more rapidly.  But, the acceleration is kicking in at too low of a tuning knob rate.  I'd like to see the acceleration curve altered so that normal rotation of the tuning knob will not cause the acceleration to kick in.  I have other digitally tuned receivers with an acceleration function that does not activate at slow tuning rates, so know it is achievable.
