Nothing has changed regarding the marshalling from 2010.
The GP rules state that unless specifically mentioned in the GP rules (e.g. targets) the series will run to the Main Shoot rules.
Main shoot rule 5 ii:
The BFTA marshalling system shall be used on all BFTA events unless the BFTA rule otherwise or the particular event rules state an alternative marshalling system, e.g. Buddy.
This is no different from 2010.
