109 cant do XXXX anymore.

Agreed that there is some delay as I wrote. But I doubt that this delay is proportional to the duration with which one pushes the lever, particularly for an electrical engine which has very fast rampage speeds. Or have you ever seen an electrical mixer taking longer to stop when using it longer? It will be almost constant as it won't accelerate until you release to button. It will accelerate a short time until reaching its operating speed. So I do think that the delay should be constant except for very very short durations of lever pushing.

And I also doubt that the delay can be very long as the ratio is not that excessive and the electric engine will work as a braking system as soon as it is ordered to stop.
