I agree, I think being told that you should have doubled near the DP,
CP or TG is additional useful information - it gives you feedback on
whether you completely mis-read the situation (thinking you were under
the cash point when you had almost crossed the TG point for example)

And I agree that's clearer as well. You could even go further to say
Missed double (below CP) and
Missed double (above CP)
Do you want to split "Missed double (around CP)" into two categories
(making it 4) or combine the 3 missed doubles to 2?

Let's see what orderings are possible:
DP <= CP <= TG - normal, as above
DP <= TG < CP - can't happen, by definition of TG
CP < DP <= TG - can't happen CP must be >= DP
CP < TG <= DP - can't happen, as above
TG <= CP < DP - can't happen, as above
TG < DP <= CP - all doubles are wrong, all no-doubles are right
So the only extra requirement is that the first test is that if a
double is offered, you are below the TG point, if not it's a
Wrong double (above TG)
A test for TG < DP is necessary so it doesn't fall into the normal case.

With the above test, this is no longer relevant.
What I'd love to see added is a change to the graphs so that rather
than being bar graphs, the areas became trapezoids with the top of the
graph being the fully live cube values and the bottom being the dead
cube values
live

I don't know if this is possible with GTK, but I think it very nice.
That's a good idea. But I neither know what could be done with GTK+.
Alternatively, one would have to draw a graphics, maybe with LibArt.
