I've been climbing for about two years now and a lot of the language around grades has been that they're all subjective and not helpful. I understand that for some it can be what causes a mental block in progression, but grades exist for a reason don't they? They can't be all subjective? How do you know if you've progressed in terms of difficultly and overall technique if not for some sort of value telling you you're moving forward? Genuinely looking for some explanation because in my experience this far throughout different gyms the grades seem to roughly in line, but also have helped me personally want to push myself to get stronger and try harder. Would love to know your thoughts :)
