What you state is totally bogus, Evacuation demonstration will and can not take place before Table Tops,
The order it is done in is;
1. Conformity
2. Table Tops
3. Emergency Evacuation & Demonstration
FSIM 8900.1 Volume 2 Chapter 30.
There are no Fee associate with it and the "mini evacuation and ditching demonstration" does not exist.
It is a plain Evacuation and Ditching Demonstration, each event will require a separate form.
The event is timed, the time is calculated based on installed seats, the passenger demographic is very carefully planned, a certain % have to be over 60 yrs. of age and a set % have to be children, plus a life size "doll" that have to be carried out.
Every CPM (Certification Project Manager)will have their own idea on how to get it done, when time starts and when time finish, in addition some CPM are allowing sneakers other not.
This is a test on the cabin crew, how they handle the situation, Briefing Passengers, know their positions, open doors slides etc.
