Hypothetical question... or maybe not... shock pressure at sea level vs elevation

Suppose you send your shocks to California for a revalve. When you get these shocks back, they seem way stiffer than you think they should be. How much of a difference would recharging these shocks with nitrogen at sea level, effect the shock dynamics at my current altitude of 5400 ft? not enough to notice?? Or would you... Just something I have been thinking about... Curious to hear thoughts on this.

 

Probably ansered my own question. Late night imsomnia for ya!!
