Re: [Bug-gnubg] Fwd: Listing JSDs in rollouts

[Mary Hickey]

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?
