A couple of interesting things here:
When watching the original creation--"Second Chance""--I've often wondered would it have been more difficult to do the same technique on the "SC" board, since it seemed to move around at a considerable faster speed? I think so, but don't know for sure!
I seem to remember this being discussed here at some point and someone mentioning that a similar incident had occurred on Second Chance. I don’t remember much more than that but I’m assuming it was less dramatic than Larsen’s run.
When I recall it being discussed here years ago, someone threw out that a contestant had won upwards of $70K, which seemed improbable, though not impossible.
Looking at the show's intro right fast, I counted an run of 11 safe spaces in the light sequence, which landed on the big money space at least once. I could cede that a contestant figured out the pattern, and thus figured out safe strings of the sequence that more often landed on the big money space.
