Cube action confusion (for me)

In the position shown below, at many scores this is too good to double, at other scores is is simply a double/pass, and at some scores it is not a double.

I am most interested in those scores where it is too good or not too good, and how to make that decision over the board. Of course, you have to get a good estimate of gammon wins and "market gainers" where your opponent might get to a take on the next sequence, but even if you make a perfect estimate of those numbers, the key to whether or not it is too good is knowing the differences of the value of gammons with the cube at 1.

So, since misery loves company, how many of you would know, over the board, which of these scores it is too good and which ones it is not? And would you get this right over the board?

4away/4away; 3away/3away; 5away doubling 3away; 3away doubling 5away; 4away doubling 3away.

How many of you know the 1 cube gammon values at these scores or are able to calculate them reasonably well over the board? (Blue on roll, cube action.)

Blue on roll, cube action?

 Too good at 4away/5away and 4away/4away, but not at 3away/5away or 5away/5away. No double at 2away/5away. Too good at 3away/3away and if 4away is doubling 3away. Too good at 4away doubling 2away; but D/P at 5 away doubling 3 away.
