From the article linked above: "In fact, cupping reduces full-throttle engine speed 150-300 RPM below the same pitch prop with no cup."

This is the key point. Same prop with more cup (if done right) will be faster or run lower RPM at top speed. If you compare the ACME 537 and 1161 as I have you can see a slight difference in top end speed at WOT of about 1.5 MPH. But there is virtually no difference in hole shot.
