After notifying the operator I drove past CS @ 23:04 and arrived at Y-Mid station @ 23:09.
Started filling CP3 @ 23:15, opened the exhaust check valve bypass valve, then opened LLCV bypass valve 1/2 turn, closed the flow 105 seconds later.  3 minutes later I closed the exhaust check valve bypass valve.

Started driving back from Y-Mid @ 23:28, arrived at the CS @ 23:32.
