Okay, I was 3 hours into watching the replay and counting trucks when I noticed Rover 2 chat has picked up the count again. So let’s go with their numbers instead of me going cross eyed trying to watch this for 12 hours.

Rover 2-

12:45pm- 144 trucks

13:15- 150 trucks

Starbase Live-

12:23pm- First pump truck lowers
