Ethan, thank u very much for your reply. I respect your understand. The 1st inversion is hard to mis. But the 2nd wasn't realy sure about it. U say the 2nd inversion is at the end of the second , what u mean by "the second" ?
I guess, "second half".
BTW, depending on your definition of "inversion" and on the actual banking of the curve after the first launch (whether it's more than 135 degrees) you might consider counting a third one...
Anyway, speaking of it, I never really understood the concept of defining inversions for a flying coaster. Neither a 0-g-roll nor a wingover/barrel roll really turns you upside-down. For this it takes a section of a vertical drop, like in a vertical loop or variations of it like to famous
Brezel-loop. So it seems somewhat arbitrary to me. However, people seem to be happy with calling an inversion whatever would turn you upside-down, if this track would be ran by a train of an (inverted) sit-down coaster. Well, fair enough.
