That just gave me an idea....
Lets say you have a 100 cubic inch (air tight) container that's filled to 50 psi. If you compress this space to 75 cubic inches, wouldn't the psi rise? So by compressing your forks aren't you also raising the psi as there's less volume?
That is an excellent question...
fill an air tank with 70 PSI now see if you can inflat a flat car tire to 35 psi and still have 35 psi in the tank... I tried it once a hundred yrs ago or 1990something... I still had a pretty flat tire... it worked on paper
