An example is A Muerte. This route would be considered 8c+ on an old-school grade scheme, like Action Directe, and 9a, on a modern scheme.
Is it better to shut our mouths and try and not be too much like bitter old men?
An example is A Muerte. This route would be considered 8c+ on an old-school grade scheme, like Action Directe, and 9a, on a modern scheme. It's the truth that looking back, a fundamental interpretation of the German grade 11, gave birth to what we now understand as 9a. 11 literally meant the step above 8c, but this is fuzzy stuff. Ben Moon and Alex Huber know all about this.
I'm with Squeek, surely the pragmatic thing to do is make any needed adjustment in the direction which involves the least number of routes having the grade changed
Actually that might not be so bad, I could do some hard-ish routes this year, stop climbing hard sport routes, but still continue to climb harder every 5 years or so as they get upgraded.
