There have been a number of great threads on this subject on JWD.
Every congregation has a house close to the KH that is always "not at home" and the publishers always use to "start their time".
"Drive-by's": Return visits that can be determined from the car to be "not at home".
Break rules get embellished over the years by what pioneers and publishers observe CO's and DO's doing. My pioneer group stopped each day at a Mexican Restaurant and used an awesome coupon. We ate for almost nothing, counted our time straight through, leaving a tract on the table(or letting the waitress in on our "primary activity."
A brother signed up for auxiliary pioneering, only to find his car to need overhauling. Solution: He overhauled his car that month, counting his time. I won't give you all his rationalizations.
A recent JWD thread detailed a brother's 5 mile hike to a forest ranger's cabin(no vehicles allowed). He left back issues of the mags at the cabin and counted his time both ways.
In the 60's I had a Bible study call me every morning at 8:00 to discuss the daily text. She woke me up and started my time every morning.
I recall another thread. A brother awoke at 7:00 am, dropped a tract from the window of his upstairs inner city apartment and took a shower with his theocratic meter already running.
I will stop there, but there are so many, many more.
