How about actual physics and math. In other words, if the coaster is 125 feet tall, it goes ~60 MPH, not 74. A 246 foot coaster in RCT goes nearly 100MPH!!! That's just impossible, and it is easy to fix. Also, calculation of ride length and speed is incorrect too, presumably from the funky physics model. For instance, I have a coaster that is 4,426 feet long. It has an Average Speed of 21 MPH...and it takes 110 seconds to go through the course. If you convert the average speed to feet/sec, and work the math, it should take a train 2:20 to go through a 4,426 foot track at an average speed of 21 MPH. NOT 1:50. Very strange, and should be easy to fix.
