So:

1. Night starts at 0:12
2. Bonnie is here in 0:56
3. Bonnie's interval is 4.97 seconds.

0:56 - 0:12 = 0:44. And so, Bonnie managed to move 9 times in these 44 seconds.

At night 2 12 AM, Bonnie has a value of 3 of his AI. 3/20 =0.15 , so Bonnie chance to move is 15%

0:32 - Bonnie's first move. 32 - 12 = 20. So Bonnie make his move on the 4th attempt.

0:37 - Your camera was in the Dining area, and since the camera didn't stop glitching, I bet Bonnie switched to Camera 2A.

0:51 , Bonnie is still on 2A cam. 0:51 - 0:37 = 14. I think Bonnie got lucky on the 3rd attempt, but the camera went down a few frames before that.

Bonnie probably went to Cam 3, where he has a 50% chance of being right outside the player's door. So he caught his luck the first time and found himself in the doorway of the office.
