This is teeing up for a sudden, swift, and " seemingly " unexplained drop. It's as if spy has dared farther and farther out on the ledge, and the footing is becoming ever more narrow.
There are gaps below, specifically, there is a gap at 186.63.
I can't find any gap that has not eventually filled on spy.
If one thinks they can, then they need to scroll back further and realize that's the " unfilled " gap is a back fill of a previous gap.
