Hello,
I've just received a reply from X-Rite tech support.

You are right, the Black Start curve option has changed the way, how it works. I have attached a short explanation, why it has changed. I also need to do some tests to understand how it acts now and here is, how I interpret it, to get some orientation, what value to select:
Samples:
- Select a Black start of 100% to get Black into tonal CMY values from 0-100%
- Select a Black start of 70% to get Black into tonal CMY values from 30-100%
- Select a Black start of 50% to get Black into tonal CMY values from 50-100%
- Select a Black start of 30% to get Black into tonal CMY values from 70-100%
- Select a Black start of 10% to get Black into tonal CMY values from 90-100%
I will address the point, that the Help text has not been updated, to our product management. For the meantime I will create an FAQ.

The PDF document the person mentiones is attached to my post.
What aids to the confusion, is that there are no units displayed, either next to the black start slider and on the X axis. I would add ' L* ', but who am I...
Regards,
Yann
