Need help on regulator

Well Ive hit 2000 shots so I decided to break down my Edgun 22 long
And adjust down regulator slightly. Everything disassembled fine. Got down to reg and it was loosely screwed together. So I started taking it apart. Removed lock screw top piece to expose washer pack inside. Needless to say I had it tipped And all the washer came sliding out onto towel. Washers stack stayed slightly in order but first and last few flipped around. I’ve watched Oldgoats video and can see he also has total of 12 washers and they look to be stacked in pairs. My stack looked to be organized a bit differently so I reassembled as best I thought it should be. Needless to say kept stock 130 bar set to make sure I had stack right. It’s locked down to 400 fps. HST won’t get it past 450.
I need to know order/orientation of washer stack please.
