Configuration 2.4-5.5 corresponds to 1-10?

That’s correct. If you look at the table in my post #4 again, they use to top frequency of the destination region to name the configuration, for example config 2.4 is the first one, config 5.5 is the 10th one.

And if you look at the gain curve charts, you will see the dark red/blue vertical bands which represent the destination region, and the very light gray bands to the right of them representing the source region.

and the best configuration for compreenshion people with mask?
