I stopped keeping a log book 15 years ago...For sorties I used a ratio of each of my SIC/PIC/Instructor time over my total time to divide up my mil sorties accordingly. I also just WAGged my cross country time at about 80-90% of my total non student time. I've gone back and forth on other time but will probably eliminate it from my calculations since I can meet the minimums without it. Good discussion.
