I used to just start writing them down as people tell me. "Okay, Rin has a 16" (writes "Rin 16" near the top of the sheet), "who's next? Nalya? You have a 4?" (skips down a bunch). "Mijelle, you've got a 15" (writes directly below Rin) ...
I roll the enemy initiatives while the players are rolling theirs, and then I poll table. "Anyone have 20 or higher?" then I jot those down and the enemies that have more than 20 in order on the board. "Who has 15 to 19?" and so on.
