If you select
the graph option on the DD options screen you will get the results presented
to you like this:
The bottom left
button lets you select different data views:
- Hand shape

point distribution

count distribution
- Opening bid
distribution
- Skew (hand
shapes)
- DD
(distribution of number of tricks made in each analysed contract)
You can export this data to Excel if you have that software, or print it to
a printer or file.
Clicking on any
graph bar gives you information about standard deviation of the result and
the percentage of all outcomes represented by the bar - very useful if the
total hands are not a round number like 1,000 which is very likely if you
use the filter options below.
Set a filter
brings up this menu:
You can now
filter out certain hands. So as an example if declarer had opened a weak NT
(12-14 points) and you were trying to work out whether 10 points and 6
spades was enough to invite the graph initially will show how often 4S will
make.
With the filter
page you can remove the 12 counts (and 13 counts with 8+ losers if you wish)
to see what happens when partner accepts your invitation.
You can also
look at trump support and see how often it makes opposite 4 trumps or 3 or
2.
Or you can set
the tricks made to 10+ and look at the various graphs then try again with up
to 9 tricks and see what you can learn that helps you decide if you should
invite and when to accept an invitation.
If a filter is
set the Excel export will only pass data on the filtered hands.
