RS Forks - Negative Air Chambers

Another quick question from me!
Someone told me that whenever I adjust the pressure (pump!) of my negative air chamber, I should always have the fork & bike upside down.
Is this true?? And if so, why?

be aware that you may need to cycle the fork a few times if you get an oil lock in the compression side.

I have noticed myself sometimes, when I set a pressure to the negative chamber, remove the pump, refit pump to valve, and then get a slightly HIGHER reading for negative pressure!! Yes you read correctly - a higher value, with forks right way up.

But strange though it may seem, turning my forks upside down with pump attatched seems to alter the psi reading on my pump gauge.
Oh well - close is good enough for me!

as you are not doing that the air you here is the air coming out of the pump.
the reason the pressure is less when you attach the pump is because you have to replace that air that was "lost" from the pump.
whey it changes when you turn the fork over. oil clogging things and causing the gauge to miss-read.
or the pump leaking or the pump arm moving out changing the volume.
