Maximum is 0.9, to leave some headroom for fsync and any other things that need to happen during a checkpoint.

I think it might be more user-friendly to make the maximum 1 (meaning as much smoothing as you could possibly get) and internally reserve a certain amount off for whatever headroom might be required. It's more common for users to see a value range from 0 to 1 rather than 0 to 0.9.
