The reality is the standard isn't currently enough to ensure compatibility which is why each rim company is posting what specific tires they have directly tested and what specific pressure they will sign off on for those tires.

i know no one cares or writes me off but I am also a wheel company. The tech isn't good enough yet for sure. Also - there is still not any solid benefit for the riders. These are all tiny marginal gains. I am still sitting here asking, "why". I mean if you sat here and told me "riders will effectively be able to run setups allowing them a 10w gain at 20+mph I would still question that as being a real benefit but it would at least make a solid case for the change. No one is claiming that publicly at least. So... Yeah it's coming. It will improve, but what's the actual point for the rider. Seriously.
