Overfilled CP3 with the exhaust bypass valve fully open and the LLCV open to 100% via the MEDM screen (different method).

Flow was noted after 64 seconds, then the LLCV was returned to 24% open, and 3 minutes later the exhaust bypass valve was closed.

Note: This morning I drove to Y-Mid to monitor the behavior of CP3, to make sure that we were not dumping LN2 on the ground, after the drastic change on LLCV setting (before was 17 now it is set at 24% open), I spent 25 minutes there and only observed 1 "burp" of 1 second of LN2 gas visible as a steam cloud, no liquid was noted coming out of the exhaust line, so it appears that the system is good at 24% open.
