@ww counterpoints: wicked this one's got its low point just before the final braking section coming into the station and cannibal which has a tunnel going six meters underground
the start and end of any coaster need not be at the low point, and often, the station is at a middle point, roughly speaking
though, i can see what you're getting at, but, at least in myself, the emotional coasters, they tend to fall off at a middle or perhaps low neutral.. the lowest points, for as awful as they can be, are only temporary... and even if the coaster breaks down and you're stuck in the low point for a bit, it's still only temporary.. it might just take a bit of work to return from
massive tangent: i've gotta get back out to lagoon at some point, gosh, wana ride some roller coasters so bad... wicked is awesome... must've spent a couple hours riding that one repeatedly with my sibling around the time cannibal released :3
