It's a real pain-in-the-butt for a dyno operator to change it. They may need to override the system defaults every time they do a dyno run. That's not practical for a shop trying to make a profit. I do it on my own graphs, just because I'm not a shop and I have too much time on my hands.

When I first saw this more than a year ago with my own dyno results, it confused me too. That's when I noticed that the two numbers were on different scales. As soon as I corrected the scales, the lines intersected exactly where I expected.
it all makes sense now, thank you.
