It is less than half a second ;)
I'm not sure, but we could try later to add a timer to finish up the ramp-
There could be (not foreseen) side effects...
At this point I think this (series) is a good start and it is better than what 
we had.

BTW: I'll wait for the verdict on the series and I will send a fix for the 
Handsfree pop attenuation also.
