@licquorice I was trying to put it in simplistic terms rather than go into all the technicalities. I know there is a lot more to overheads but why confuse someone. I prefer to just give them something they can understand.
Err no. Overheads have absolutely nothing to do with acks.

Kind regards
@licquorice Err yes they do. For instance a speed test only uses the first three layers of 7.
