Hi Mary,
I'm glad you like the suggested layout. I wouldn't bother with an option for
this, once it is agreed. We should just take a decision and go with it. Gnubg
already has myriad options, some of which add little functionality but much
complexity.
Speaking of options:
You already have the option to use percentages. You can set it at:
Settings\Options\Display\GWC as percentage
Which gives:
1. Rollout 8/5 6/5 Eq.: -0.6879
34.62 7.92 0.30 - 65.38 24.16 0.96 CL -0.4766 CF -0.6879
[ 0.09 0.07 0.02 - 0.09 0.11 0.03 CL 0.0022 CF 0.0064]
I tend to use the decimal layout, but you're correct that it takes an extra
digit. I might change my settings and see if I like it; 34.62% is probably more
natural to a backgammon player than 0.3462, and you are also less likely to
confuse 10.00 or 1.000 gammons than 0.1000 and 0.0100 gammons. It also helps
distinguish the result breakdown from the equity.

Hi Ian,
I'm with you on making the rollout reports easier to read. For those who prefer
the old reporting, there could be an option for users to turn on if they
wanted, with the default being the new easier-reading variety.
What would you think of also converting the profiles to percents instead of
fractions, too? It would get rid of those first zeroes. You could still leave
one there in the cases where the value is under one percent, as is often true
with the backgammon numbers. Spaces could be inserted in the line as needed to
make all results line up when they are printed or cut-and-pasted elsewhere.
Your first line in the example:
0.3462
0.0792
0.0030
-
0.6538
0.2416
0.0096
would become:
34.62
7.92
0.30
-
65.38
24.16
0.96
Do you think that would be an improvement?
