Ian,

I certainly didn't intend to ask GNU people to deprive you of a valuable 
tool for theoretical work. I was just puzzled but I got your point now and 
understand why you may need this 4th digit.

... BUT ...

On your part, you have to realize how disturbing this additional digit is on 
a daily basis (sorry, no offence intended, but at the end of the day, that 
is what GNU is meant for), when you have to readjust mentally almost every 
single position's equity for, say, a 11 pointer analyzed.

Actually, since this discussion started, I realized the 4th digit is also 
displayed now when you export a match in HTML, as illustrated below.

*FRENCHKISS moves 24/20 13/8

# Ply Move Equity
* 1 1 24/20 13/8 -0,1041
 44,80% 10,73% 0,23% - 55,20% 12,09% 0,35%
 2 1 13/9 13/8 -0,1211 (-0,0170)
 43,94% 11,73% 0,25% - 56,06% 12,73% 0,61%
 3 1 24/15 -0,1282 (-0,0241)
 43,59% 9,39% 0,17% - 56,41% 13,52% 0,29%
 4 1 24/20 6/1* -0,1312 (-0,0272)
 43,44% 10,21% 0,20% - 56,56% 12,47% 0,41%
 5 1 13/9 6/1* -0,1495 (-0,0455)
 42,52% 11,54% 0,25% - 57,48% 14,50% 0,84%

Also, this has been like this since the very beginning of HTML exports, but 
for practical purposes of reviewing a match, I have to add I would be quite 
happy with percentages displaying only one decimal place (only for exports). 
This would make it much more readable.

Plus, there may be out there casual users of GNU that would be quite happy 
with 2 or even 1 decimal places... so IMHO the best solution - if not too 
much time consuming - is to include this choice as an option, I mean a real 
option, not a 'hidden' one as Jorn suggested
