I'm not sure that's entirely correct, since that would mean...
Noise Level * Volps = X10 Signal Strength
and Noise Level multiplied by anything is a bad thing unless you jiggle the numbers in your favour.
Since the application of Volps (JV) has an amplification effect upon X10 Signal Strength (XSS) the Noise Level (NL) would effectively be muted amongst the amplified XSS.
Therefore, although your measure of reliability is mildly amusing, it cannot be considered entirely accurate. It would be safer to say that
-JV
JV*XSS=NL
That said, I must admit that it's been pretty long and complicated day and the writer may have achieved that state of mind where 'talking bollocks' (google it for wiki) takes precedence over mathemagical (yes, I know) equations, particularly long and complicated ones that involve multiple variables such as WAF, PCE and CARM (Wife Approval Factor, Phase Coupling Efficiency and Cash Allowance Remaining at Month-end). Also it's been a long time since I went to school and I've forgotten an awful lot more than I remember, and when you add in my convoluted SOH it can all get pretty complex.
Anyone who isn't confused by now obviously wasn't listening properly
