A niggly bit, but with the pressure relieved when the suspension is completely unloaded, the result is indeed some positive pressure in the fork headspace.

Besides, my bike works better with the forks bled than with them pressurized (not relieved). That's my take..it's my bike...I ride it...so, it works for me!
I like toemaytoes. If you prefer tuhmahtoes then order your burger differently! ;)
