I achieved this WR ever so casually on Teleport Training.
Unfortunately, others caught on to my tactics, and after a battle for the WR, Rosie eventually snatched the WR with 8.895 seconds, even though I had later improved it to 9.358 seconds. No other video evidence has surfaced yet, so I'm posting this.
This actually was only possible because of a glitch in 1.7.36 or so, not because of a new path.
Gem Hunt is based on score, not time.
Awesome SCORES, not TIMES...
