You sound like you want to be fairly thorough.
Good for you. I know a few people who simply write "Two way with 'X'" and call it good.
I also know people who fill up the entire page with details about the jump. I'm not quite that anal, but pretty close.
What I typically do is to start the entry after the dirt dive while waiting for the plane to come down. Names of people, planned exit, planned points on the jump. I use the actual names of the formations (I don't use the letter designations). It might be, for example, "Bow exit, then round, then satellite, then break in center and spin pairs, back to satellite, back to round.
After the jump, I'll write down what really happened.
Also, any notable things about the rest of the jump.
Usually a note about the quality of the landing pattern and actual landing, anything unusually good or bad, anything I want to remember.
Generally, I'll record:
Who was on the jump. Usually just first names.
What was supposed to happen (done before the jump).
What actually happened. This is NEVER the same as what was planned.
Opening quality, perhaps with a quick note about anything different I tried when packing for that jump.
How good the pattern was (or wasn't).
General accuracy (not in feet, but 'close' or 'not close' or something like that).
And anything else that was noteworthy. This could be something that was said or happened on the plane, something really cool or really bad in freefall (diving down and getting to my spot is cool, nearly having a high speed collision is bad), something under canopy (I've had an eagle fly past me while I was under canopy, that was really cool).
It's your logbook and your entry.
Write down whatever you want. As much or as little.
I don't know anyone who regrets writing down too much.
I know a few who regret writing too little.
