So if I'm understanding correctly your max 6 days on is primarily to assure the "1 in 7". Does that work out to being able to do three stints in a row of that, followed by off time at the end of one month and into beginning of the next (14 days)?
And am I correct in assuming you can drop trips into open time for reduction in pay, which can be made up with pickups in other spots?
And how realistic is this after 6 months to a year?
