Thanks a lot for getting back.
Changing F-Curve scale here doesn’t seem to make any real change to the actual values (select them in the graph editor and they’re exactly the same), seems to be something to do with Auto Relative viewing as far as I can tell (the R pops up beside Position X). Taken a trip to Cineversity to try and understand that but as far as I can tell that’s just for convenience of seeing curves together no matter the value.
Happy to be corrected here as I am struggling to get my head around this.
