The CCG has decided to make it policy to not start loading elevators until 5 minutes before the scheduled run time. The organization is not perfect, sometimes the last load will leave a few minute before the listed run time. If you are late and you really want to go, hang around on the platform; it is not uncommon for a final group to gather and launch up to 30 minutes after the official run time.
They are a loose volunteer organization, sometimes things go wrong, but things work well most of the time and they really do get first-time cold callers through the VP on a regular basis. If something goes wrong on your first trip with them, please try again. The current success rate over the last year (based upon reported runs) is 90% between VP & CFO. Meaning 90% of the toons who enter the elevator dance at the end.
