That HelpDesk is ridiculous. As mentioned, who’d spend time on choreography to avoid a max -.10? Furthermore, the examples shown prove most, if not all, evaluations in this sport can’t be boiled down to 0.0 vs. -.10.
The difference between no movements > the series of fwd/swd rolls shown needs to be greater to properly score efforts that fall between. “Artistic,” composition, or wholistic (across the entire routine) deductions should be converted to evaluations of: -.20, -.15, -.10, -.05 | +.05, +.10, +.15, +20.
In theory, this could also be applied to updated CRs (i.e., 3-element mixed / dance series on BB or FX). This would assign value to components of a routine that can’t be broken down by individual letters, and to more subjective aspects of the sport, IMO.
