Nice run and throw.
I did take out Berg without using a second BC in the run before this was featured, but from the other side which made the results hit-and-miss (as he’d often be just out of range by then). Tbh it hadn’t crossed my mind to throw from that side, and it looks like it works well.
On watching your video, I was wondering if you could maybe wait in the cut-scene longer and stash the duck in the truck, and still arrive at the same point to get Berg? If it works, it might take a few more seconds off the time.
