How about, "The Market Window tab on the Theory window".

Your calculation is indeed correct. Sorry.

Yes, I think this would help.

I agree that GnuBg is arguably correct, but I still found it confusing.
Perhaps the truth table for match cube reports should go:
Double Action Take Action
Not Too Good No Double Take No Double Take
Not Too Good No Double Pass
Not Too Good Double Take Double Take
Not Too Good Double Pass Double Pass
Too Good No Double Take Play On Take
Too Good No Double Pass Play On Pass
Too Good Double Take Too Good Take
Too Good Double Pass Too Good Pass
I've used "Play On" for the cases where you are Too Good and Not Good
Enough. It is less descriptive but shorter and easier to fit in the space
available.
I don't think there is a situation which is theoretically Not Too Good, No
Double, Pass.
A Wrong Double About Too Good would have to be above the doubling point.
