I'll Decide ...
While I haven't been assessed at as high of levels as some here, I absolutely refused to do anything different when I was being assessed. IMHO, if it is how it should be done when being assessed, it is how it should be done all the time. And if that isn't true, the assessment system is broken.
(OK there was one exception--call me a hypocrite if you want. Once upon a time, USSF insisted that the R and AR wear the same length of sleeves. They go over it. But there were some of the old guard who continued to insist that is what we were "supposed to" do. So on assessments I would not have the ref team wearing different length sleeves, as that is not an argument I would want to get into.)
Observed.
Not assessed.
