I concur with all of your points. I read the technical threads in hopes (sometimes vain) of separating fact, fiction, and folklore. It's taken a while to calibrate my bombast filter, but even without a scorecard I've learned to tell the players.
Is FVM '
Fender
Vox
Marshall'? Here is a Tone Stack Calculator from Duncan Amps. It seems to be safe and is fun and educational to play with. It demonstrates how the various knobs of some of the classic tonestacks interact with one another. Yep, as you say, hardly intuitive.

Picking a tone stack style
There are seven flavours of tone stack to choose from:
Fender
Vox
Marshall
James
E series
Bench
Big Muff
Hiwatt
The Fender and Marshall stacks are similar in construction, while the Vox stack can be viewed as a Fender stack with a fixed mid control.
The James control was described in Wireless World during February 1949, although it is claimed that Michael Volkoff first used this type of control in July 1939. Many would describe it as a Baxandall control, although the true Baxandall control was an adaptation of the James control using negative feedback.
The E series is another (older) variant of the Fender tone control.
The Bench tone stack is named after Steve Bench who offers this design as an alternative to the normal resistor/capacitor tone stack.
The Big Muff tone stack is a simple hi/lo tone control suggested by Jack Orman. This type of sweeping control is common in FX units.
