I installed v1.31 and went with 12 hour shutdown timer and 5 fps on Thursday, 2 fps on Friday, and 1 fps Saturday. I should note that I'm in the Pacific Time Zone and currently GMT -7. My results were as follows:
Thursday - 5 fps:
Parking mode initiated at 6:47am, lasted until 10:35am
Friday - 2 fps:
Parking mode initiated at 6:48am, lasted until 1:48pm
Saturday - 1 fps:
Parking mode initiated at 6:49am. Parking mode behaved normally until 10:50am when I went to go get some food. When I came back and parked at 11:00am, parking mode initiated for 2 minutes, and then full recording started to take place at 11:17am and lasted until 1:22pm. No further recording, full or parking, took place until I left work
2 fps seems the most stable on v1.31, so I'll stick with that until a permanent fix comes out
