I am pleased to confirm that my software agrees with the Secretary's
devotee's interpretation of the tally sheet.

The beats graph showing tallies on both sides of each defeat can be
found here:

For example we can see that Neil beat Mehdi by 203:119.


Transcript from my software is below.

I used git commit d7b1f7e0563948d004be2035c2acaf5045223b4f of
  http://www.chiark.greenend.org.uk/ucgi/~ian/git/appendix-a6.git/

You can see the `options' file I passed, below.  I have not verified
