This web site has some nice pictures of aircraft cockpits, including
two gliders. If you scroll down you will find an LS-4 flying
inverted.

What caught my eye is that there appears to be four (4) varios in the
instrument panel. My soaring friends have been scratching our heads
trying to understand why you would ever need four varios in a single
glider.

Can anyone give some valid reasons why this would be useful?
