5 bar creep on last reg Fx Maverick

Hello, I noticed that the last reg on my Maverick has a 4 to 5 bar creep. I have a Sekhmet mano. Is this acceptable? I shoot with a 95 bar reg pressure.
Other question, when I take it to the range the reg pressure stays at 93 after a mag dump. Then I open the last reg to 95 bar and it stays at that. When I take it a week later to the range exactly the same, so every week I have to open the second reg a little bit???
Should I go for a Huma reg, as second reg in my Maverick??
 
Meh, it happens. Shoot at your zero when it jumps up in pressure and see if your point of impact changes. I doubt it does. I've got two or three that do that. My Impact .22 is set at 155 bar but if you you let it sit overnight or two weeks it jumps up 5 bar. After one shot, instantly back at 155. I don't sweat it.
Now if you see it continuously keep going up and up, you may need to reseal your reg, which is really easy to do.
