If you have to pull focus yourself the most important thing is to get a good feel for the logarithmic scale of the lens... keep in mind that if objects move closer or further away the corresponding movement of the focus barrel is not linear...
and remember in which direction you have to turn the lens barrel if the subject or you move closer or farther away... but that´s pretty obvious I guess...
I try to place my fingers on the lens or the follow focus knob in a way that I know my index finger rests on the 3 feet mark, my middle finger rest on the 6 feet mark etc... so I know if my index finger is in the 12 o´clock position I´m at 3 feet etc...
I try to keep the eye that does not rest on the viewfinder open to check my position and gauge distances....
I measure the length of my wingspread, the distance between the tips of my fingers and my elbow, my shoulder etc... and whenever I can I walk around on set trying to take measurements with my arms spread wide to get a feel for the distances... (looks pretty silly...)
I always select a few spots in my frame that have high contrast because that makes judging focus a lot easier...
in certain situations it can be very helpful to just try and keep the same distance to your subject if it´s in focus... in those situations I make a few mental notes to remind me of the framing I have when the subject is in focus... the distance between the top of the head and the top frameline and where the lower frameline cuts through the torso for example and I use that as a guide to hold the framing and stay in focus while following the subject...
sometimes I focus not by changing focus on the lens but by moving in or away until the object is in focus...
just a few hints... but the most important thing is practice, practice, practice... or even better, an experienced AC...
