CHP is just to satisfy ego. That said, your feeling about percent increase is sound. I have been modding high performance cars for decades and whp is golden standard. Anyone that uses crank numbers just does it for marketing reasons. As you stated, percent increase is probably equally as valid.
I also agree real world performance trumps all. The 60-130 benchmark is a big one because it takes wheel spin generally out of the equation. Trap Speeds are also super important to assess car performance diver driver skill. Either way, that is a legit point. Grab a draggy and see what kind of 60-130 mph you are running and it should give you a sense of where you stand and how much of that power is making it to the ground.
One last thing, you do realize you are on rollers for your dyno right? That doesn’t measure crank hp. You would need to have your engine on a stand to measure crank hp. They are simply using some guesstimate on drivetrain loss to back calculate to crank.
