^Perhaps you would like to read the rating guide? It explains that a rating isn't just one sentence saying "I like this ride good job." A rating here is supposed to be contructive criticism.
For example, the supports are auto-generated with little or no editing from what I can tell. Try to make custom lateral bracing on the stressed sections of track. (Yes, this semi-paragraph is about your coaster)
Really, all I can do for you is to tell you to read the rating guide. Sorry for being blunt, but the track really doesn't deserve a 9.5/10. Rarely does a veteran's track recieve a 9 or higher, let alone someone who isn't very active in the community.
