Gotta love that min day language in the contract that let's it not apply on the first and last day.

If we want efficient trips we need trip and duty rigs. If we can make 4 days credit a minimum of 20 hours, then suddenly that 9.5 hour 4 day means that the company would be paying a pilot 10.5 hours to chill in the hotel. I'd bet you anything that that'd last for about a month before the company suddenly realizes efficient trips sound like a great idea.
