I agree with your whole post.. but this is really true. The FSM does not give a pressure needed or a way to get that pressure.. At one time we discussed putting a can of diesel a specified number of feet above the IP to try to standardize this procedure.
"The bubble method was described by the late Marshell Booth" as being "more accurate than it needs to be"----Stevo
Well Stevo, all I can say is that according to my analysis of the physics involved..And the fact that the people who MADE the car suggest the drip method...I am sorry he died holding onto that opinion..and sharing it with others..
The flow rate which causes similar viscosity fluids ( hopefully exactly the same grade diesel--- but temperature will have an effect also ) to form drips is way more accurate and reproducible in trying to duplicate the size of the opening in the IP than spill rate or bubbles bubbling up from a hole.
If that was true that that method produced ' excess' accuracy... then think how close to perfect we can get it using the FACTORY SHOP MANUAL APPROVED METHOD....
