Eric,
Yes, there is a benefit from using coupled pendulums. As with any
oscillator noise is the limiting factor and by using multiple pendulums
the noise, mechanical disturbance, can be greatly reduced. Two
pendulums will suppress the x an y component and three pendulums will
suppress the x, y ans z components.
There will be a consolidated response to the "scientists" enlightening
them and showing the error of their ways.
Regards
Peter
