One CV by way example, Isis posted week of 25 March, design analysis:
# squares: 48
# piece types: 5
Piece-type density: 10.4%
Est. piece values: P1, B3, K2, Q4, M8
Initial piece density: 50%
Power density: 68/48 = 1.42  [Orthodox Fide's is about 1.25 or 1.30]
Exchange Gradient: G = 0.425, using range of values here 1,2,3,4,8
[Orthodox Fide is about 0.50, and Isis shows better exchange potential
with lower G]
Ave. Game Length projected:  #Moves = (4(Z)(ptD)/(PD)(1-G)) = 
(4)(48)(0.104)/(1.42)(0.575) = 24 Moves
So, Isis games should not be very long because small Z (board size) and
high potential advantage in exchange (low G).
Other features: River reduces value of Q.
Comments: Obviously, some values are estimates not completely amenable to
analysis.  From description only, comparing different games shows trends
in useful, compact numerical information, able to complement
clearly-written game rules.
