Overcrooks on Handrails

[Antwan]

So one side says an accidental overcrook down a handrail is a nosegrind
because you've never seen a straight nosegrind down a handrail you say an overcrook is a nosegrind.
Now I understand where This side is coming from..
But you can't really deny what is already there.. Frontside exists, Nosegrinds exist
Being dependent on if it has been done or not seems silly to me.

If the person is approaching any obstacle whatsoever
with their toes facing toward it in their regular stance
is it not technically frontside? So, Toes toward the hand rail.. Regular Stance. Frontside nosegrind?
If this is technically true you can't really say it doesn't exist, maybe it has not been done
but it still seems like a possible variation.

Mind you, I'm still learning but just showing interest and shedding some light on my perspective.
