After notifying the operator I drove past CS @ 23:06 and arrived at Y-Mid station @ 23:11.
Started filling CP3 @ 23:14, opened the exhaust check valve bypass valve, then opened LLCV bypass valve 1/2 turn, closed the flow 90 seconds later.  6 minutes later I closed the exhaust check valve bypass valve.

Started driving back from Y-Mid @ 23:21, arrived at the CS @ 23:27.
