I am finding that 200% is a little too fast for tool and weapon usage. However, specifying a real number (e.g. 1.5 for 150% speed) results in an error parsing the configuration as the mod expects an integer.

Would it be possible to support non-integral values to fine-tune the playback rate?

Edit: Taking a quick look at the code, it appears this mod works by calling Update additional times per normal time step. It makes sense why an integer value is used. To support a rational value, it should only be necessary to keep an internal counter that increments by the requested rate each time step. This would mean for 1.5x, the extra Update happens every other normal time step. When I get a local build environment running, I will try out my approach and submit a PR should it work.

Thanks! Merged into develop for the upcoming Fast Animations 1.8.
