What Does Amount do on the Develop Color Profile Setting

[DS256]

I was diagnosing a problem with a green hue printed from a B&W preset. The preset chose Profile "B&W 12" with an amount of 50.

Another print used "B&W 10" at an amount of 100 and there was no issue.

I can't find any documentation on what the Amount slider does for Color Profiles and specifically B&W Profiles. Any pointers?

Thanks

'Creative' profiles have an Amount slider which can be used to decrease/increase the intensity of the profile.  Note:  it is up to the creator of the profile to define exactly how far the “intensity” can be changed. In other words, you might see subtle or more aggressive changes on a per-profile basis.
