RCTgo

A CTR's relative excitement rating is set by whomever programmed it, so they're often in the ultra-extreme range because the individual creators set them to astronomical levels. That London Blitz CTR, for example, is likely always going to give ratings in the 50s.

A possible downside to this is that the intensity may be set to lower levels, so a coaster that would normally be too intense to ride would instead appear normal based solely on the ratings (aside from being over-the-top exciting).

It would be interesting to see someone build an absolute death coaster with a CTR like the London Blitz to see how exciting and intense it would be compared to a vanilla-train death coaster of a similar magnitude.
