Actually knowing that these guys were all highly ranked bothers me less.
Sure there needs to be a standard and yes they all should be on the same page.
But after many years people's arts tend to get a bit ideosyncratic, they tend to get the same place in slightly different ways.
Brand new BB on the other hand, the tendency is to follow a ridged "this is how its done" kinda plan.
(Please note I said "tendency" I certainly don't mean "everyone" here.
I fully agree however that the teachers all need to be more or less on the same page.
