Thanks for the references.

Where does the fiction come from that an "S-unit", presumably the marks
on our S-meters, is or for some reason should be, 6 dB -- that this is a
"correct" or "ideal" value? To me it's the same as "defining" pi to be
3.2, as the Indiana House of Representatives once did. "Defining" an
S-unit to be some value has no effect on our S-meters, any more than the
proposed Indiana law changed the ratio of the circumference to diameter
of a circle.

Check the chart to see actual input readings. I've always used the (6db per
S unit) as a general rule-of-thumb.
