Feel free to reach out if youd like a hand as I've done quite a bit of experimenting with the length and growth values. At the risk of not being able to comprehend it, could I get a copy of the equation(s) you're using? Maybe I can help find a potential solution.

Turns out I didn't need to change anything significant. The mod has been updated again with a max value of 3 for the slider.
Also, there are some visual artifacts due to the negative scaling, but this can't be adjusted without lowering performance (backface culling off/flip normals), so I'll likely leave it as is.
