Sam didn't dab or appear to dab with any part of his body. Momentary pause on a hard section. Could have been a five with a strict observer but probably a sensible clean given. Dan's ride was 100% a clean but with modern brakes, suspension and on very tight sections I think Sams was acceptable.
And for the stop allowed boys this only being as leinient as allowing riders to travel backwards under the guise of going sideways or balancing.
