You system has amazing specs.. The install looks expertly done. It should work great!

I had little cut-off valves on my gauge unit hoses and they were leaky.
Each time I opened are closed them, they lost some vac..
I think they may have been designed for holding pressure inside, and not holding a vac..

I think you read my detailed suggested procedure for, the last operation.?.
I like the idea of being able to cut off the Digital Vacuum Gauge, before bleeding in some R410a.
You don't want to pressurize that new gauge..
