@Jeje6410 asked in the other thread about why the RBR in the rain TT was standard rather than special. It made me think about the original reason I split out TTs such as the Olympic and movie one, and really, there is no good reason. (Well, there was a mundane technical reason around starting to use formulas to automate things some time after the Olympic TT, and then not being able to use them for that and the Movie TT, for example, because "Olympic" and "Movie" aren't numbers)
So, I am going to combine all the non-regional TTs. This will take some work as I'll need to slot them into their appropriate places, renumber them, adjust the historical community scoreboards, etc. but in the long run it will simplify things for me.
If anyone has a strong objection to this, let me know.
