Lee Juras, owner of Super Vel, published a report on his test of military 9 mm "submachinegun" ammunition in the March, 1972 Shooting Times. It was all well within standard pressure, including WWII German black tip.
US commercial and Super Vel 9 mm were included for comparison and also were within standard pressures. The S&W/F was higher than the Super Vel.
The lowest tested was 24,800 while the highest (Canadian 1945) was 32,500.
======================================
No. 3 pressure barrel; min. chamber; 6 inches long; WRA .225 x .500 copper crusher; tarage table 11366; 72 degrees F .. 55 per cent R/ H. Velocity instrumental at 20 feet.
Super Vel 9mm 90 JHP 31,000 (ave. pressure) 1415 FPS
Super Vel 9mm 112 JSP 31.700 (ave. pressure) 1349 FPS
S&W/F 9mm 100 JHP 32,100 (ave. pressure) 1433 FPS
==========================
And then, here's a picture of the original WW 100 @ 1300 FMJ "Q" load for the ISP in 1967/68.

Thank you for sharing your tables on stated values of Super-Vel ammo the adverised velociyy for 90gr JHP was 1465fps!!! the tested 1415fps!! thatīs the real velocity, what I did not now that this velocity was obtained at a an average of only
31000psi, when the standard non +p loads for 9mm lists up to 35000psi giving only 1150fps velocity (but 124gr FMJ)
Thanks for sharing, you have the objective evidence of the tests!!!..
Best Wishes
