What I'm getting at is that, whilst it is not "not permitted", the standard TGS video does not include such things.
What is referred to as a TGS video features taps, gaps and sidehops by definition, usually with the inclusion of some front wheel stuff.
What you're saying is a bit... "All sidehops are T-G-Sidehops, this rider does sidehops, therefore this rider is TGS."
That's just not true.
CLS and Tunnicliffe are the best examples of TGS. Whilst there is some creative flair, it was a common point of distaste at the sheer lack of it - concentrating almost solely on going big.
There's a few clips of Danny Mac doing sidehops and taps. Gee, y'know - I think I've seen him do a gap or two, as well. He must be a TGS rider after all.
