Yes but amongst those officials we do have some solely assisting. Well I know of at least one that does because that's what they want to do.I've thought this for a while, it'd be a great way of freeing up 10-20 L6/7 officials each week at step 6 in Cornwall.
I think the flaw in this idea is that L4 officials need to have a minimum of 10 qualifying games each season and a qualifying game must have 2 neutral AR's I believe.
I didn't know about the assistant thing, but I also don't know how that is tracked because only the R is appointed in MOAS.
Also can't see where you draw the line... Do you start taking from step 5 too?
(welcome to RC btw )
