With this option the procedure is applied looking for γi but setting ν=0 and θ=1 as in the original
Zermelo paper. The γi are in the 'Z Pts' column. The column 'ZN Pts' is the same of 'Z Pts' but with
the greatest γi set to 100. The method does not broken the tie in a round robin tournament and is not
particularly useful in this case because the ranking is the same of score percentage. In Swiss
systems it turn out to be much more useful.
Option: Zermelo Score System Extended
With this option a panel prompts the user to choose how to perform the calculations:
The user may ask to find both parameters ν and θ or set one or both to some value.
