If the PDGA just issued a suggested standard, not that it would impact compliance yet, but with a view that some day in the future, depending on how well/quickly courses were able to comply, it could become a requirement. Then responsible course maintenance and installation would surely start to coalesce around that standard.
Maybe we will just disagree. To set a standard now, that is not required, I don't see how it ever becomes required. There will always be a large number of courses that can and never will be able to be compliant. We take them out of the ground? Refuse to sanction any event or league there? In addition to maintenance of several courses, my club helps support, we now need to start fundraising to put in or replace pads?
I get the concept of standardization, but the practical, pragmatic, logistic application here is not realistic....again, IMO.
