```I just found an interesting feature in Frank Bergers BgBlitz. It gives you
the ability to analyze the games in a match database.

It reports the following for one of it's databases (the largest one of
course).

Average Number of Moves in a Game
=================================
All Games  : 20.90  (9423 games)
1 Pt Games : 27.42  ( 342 games)

Maximum Number of Moves in a Game
=================================
All Games  :   85 moves
1 Pt Games :   68 moves

Total Matches 2806
Matchlength    Avg. Games      Total Matches
============================================

1            1.00            350
2            1.03             59
3            2.35            634
4            2.75             12
5            3.83           1184
6            4.00              1
7            5.02            492
8            6.00              1
9            7.24             42
11            7.81             31

Hope this helps.
