I guess that's OK?
I bet it'd be fine, it looks like it will be going plenty fast enough, so I'd guess that accelerating further wouldn't be necessary.
As it is, speed off the rail with C/C is just under 50 fps.
I bet that's fine as well, it seems to me that 50 fps is a very conservative number with plenty of margin. (Cue famous last works from my place of employment: "It's fine, just ship it.").
