As stated in the comments on YouTube but still not changed

Sure. This will not get changed as BP ALS Version does not use this curve. If you have watched my videos you can create easily a own data table row. Sadly I am very busy and can not provide a fix at the time of writing.

As usual I am very open to pull requests.
