Dear Gerhard,
also a Happy New Year to you!
Regarding the topic you raised, I can only reiterate what I mentioned about the thread generated by Guru, EA2IF: The art of calling at the WRONG time. in our last discussion of this kind in A little bit of respect to activators.
The sketch Guru shared is so simple, easy to understand and full of truth. Life could be so easy… 
I am looking forward to our next QSO and promise at least to try not to prematurely break into an ongoing one,
