I can only say that it is a bad compression job and it is probably possible to
compress it to 1 mb.

My calculation is as follow:

1)It is no problem to have average of 6 bits per move(you only need legal move
generator and remember the number of the move and usually the number of the
legal moves is less than 64 and to compensate the few cases when the number of
moves is more than 64 you have a lot of cases when the number of moves is less
than 32 and you need less than 5 bits for a move.

2)a game has average of less than 133 plies
3)133*6M<800 bits per game=100 bytes per game
4)100 bytes per game*11358 games is only slighly more than 1 mbyte.
