This has been and continues to be a superb discussion. I missed the 'angry' words, but still completely detect the passion and desire to give sound advice.
Prudence in this vital area (brakes!) means testing with and without the proportioning valve.
Right now, I have a creeping pedal, so the PV is not my initial issue, yet will get its due during the rework.
Chris Bell has been supremely helpful to me, reaching out personally to assist.
Looking forward to more discussion.
