Skout Everything Skout EVO and Epoch

Hi just wanted to jump in and post a picture of a 5 shot group, shot at 100 yards, The green dot is 1/4-inch, with a Skout Epoch 35-inch barrel in .22 cal.

I have the compact that I received a couple weeks ago. I know that it's normal for these to leak some, but for people that own this rifle, can you chime in with how fast yours leaks? I lose about 500psi a day with this one. I know it has a smaller air volume with the 300cc bottle so it's more noricble, but what is considered "normal" for these?
 
I stopped shutting my bottle valve off, and it's been about 3.5 weeks since I used it last and the doesn't seem to have lost any air, it used to, but I'm wondering if the regs have bedded in a bit, I did replace some of the O rings with harder nitrile one a while ago.
I lose about 1000 psi over two days when I have it stored.
