This is the way I do it, mostly. If the controller makes it clear
that I must take off immediately, I acknowledge the clearance and also
indicate that I'm actually moving. Conversely, if the controller does
not make it clear that I must move quickly, and if for some reason
there is any significant delay between my readback of the clearance
and my actual take-off, I will advise the controller when I'm actually
rolling.
