for a recording angle of 180 deg you need S= -6dB relative to the M mic

Around +-0 dB the recording angle changes by approx. 10 deg/dB

This comes from an official MKH series brochure, with a separate section about MS stereo. It does noet exist anymore on the Sennheiser website, nor on the internet ... It should linger around in the remote forum - if anyone can find it ?
I'm not 'that Jim' but is this the paper XY and MS Stereo Recording Techniques by Manfred Hibber, that you were citing?
