I've noticed a ton of Newton coasters uploaded seem to have some problems with pace. Newton 1 and Newton 2 do let you know how fast the train is going at the end of each segment, but has anyone paid any attention to that? I am assuming very few people have, as the information is presented in meters per second and most people are lazy. So I would just like to say this.
I think most people that are finishing a Newton coaster, import into NoLimits and do see the lack of pace in particular areas. However they disregard it and just support the damn thing. Newton 1 and 2 designers, as a tip I would like to say export your design 3 or more times through the creation process BEFORE you finish your layout. Set you coaster as a shuttle in the settings and ride that in the NoLimits simulator and see if you have a pacing issue. If there is not you can simply continue designing and check again later. If there is, you can then go back and fix it without the hassle of going back tracking and changing a completed layout (the reason people say f*** it and just upload it the way it is).
