Chess324 Top 15 Round-Robin - Clarity 7.2.0 added

[Modern Times]

Just to re-cap, this is a Top15 round-robin tournament where new versions replace previous versions, and new entrants cause the bottom engine to drop out. As such it is not a ratings list, I'm done with those. It is akin to Graham's amateur series in a way, although I have just one "Division". And I play a lot more games.

Clarity 7.2.0 enters the tournament in 13th position. Ordinarily that would cause Lizard 10.4 to drop out, but it and Rebel 16.3 are for all practical purposes equal, so I've temporarily made it a Top 16. When a new engine comes in, then both of those will drop out to make it a Top 15 again.
