Indeed it is. It's a bit quirky and certainly what I'd call a "Beta" file, but it works, and works well so not at all complaining about it! I only asked for 8k, but it soft cuts at 8 and hard cuts at 8200. I'm personally not comfortable with the piston speeds at 9000, so intentionally limited it by asking for the lower limit.
I'm actually glad its not out in the wild, can only imagine the horror stories that would arise spinning a shim over setup to 9k lmao.
