They could keep it simple AND do so much better explaining what's going on.
If you believe Tim, then you think the scores are based on height and sticking a landing?!?!???
They could do a MUCH better job explaining the execution score. Remember the 10.0 system??? WE STILL HAVE IT. The execution score is out of a 10! Seriously... they think it's more helpful to create their own BS green/yellow/red, then actually explain that errors come from missing handstands, bobbles, form breaks, body position?!? These are things kids with just a couple of years of experience can pick out.
THEN they could explain difficulty score; "Ok, so the gymnast lost 1.2 in execution... but they did 6.0 in difficulty because of this cool combination... and most people do 5.5. So decent execution with extra difficulty beats perfect execution with little difficulty." THAT IS THE REAL GYMNASTICS 101.
I guess explaining a little bit about whats going on and a little arithmetic are too complicated??? But somehow it's important to include skill names (or make up new ones) that really don't matter at all
