Tuning Reg pressure drop question

Is the gun broken in yet-? 

I wouldn't worry about it unless already broken in. Have you shot few shots right after filled then still at100 bar-?

I'd worry if the accuracy is crap and cover the Reg manometer with a latex finger cover balloon to hide it till gun is broken in.

I wouldn't be a chrony watcher either up unless gun is inaccurate.

Only worry of its not accurate.
