@mijostyn OK, I found my Martin Logan PBK (Perfect Base Kit)!
You mentioned this:
Run the program then turn the midbass down just a little and the bass up as far as it will go. Then start decreasing the bass a little at a time until things sound right to you.
As I recall there is an Automatic and Pro option for the PBK program. I don’t think the Auto program allows for any manual adjustments. Not sure about the Pro. I guess I’ll just try running and see.
You also mentioned this:
If you do a lot of listening from one listening position just keep the microphone at the listening position for all measurements. If you tend to listen more as background music then use the 5 locations as per instructions.
ML say this, but I think I’ll stick with your advice.
IMPORTANT! Even if your room has less than five listening positions, to ensure optimal sound, measurements must be taken from five different positions. Each position should be at least 2 feet (61 cm) apart. Focus on positions around listening locations.
