Owl Computer Chess Engines Rating List #5 - All Versions

The 5th Owl Chess Engines Rating List released with completed 4 round gauntlets of Protector 1.5.0 and 100 round matches of Vitruvius 1.11C.  Protector is in rank #38 while Vitruvius is in rank #17.  The top positions essentially remained the same while the lower ranks were shifted due to the 2 new entry insertions.  Next in the pipeline of 100 round matches are Black Mamba, Hannibal and Hiarcs to fill the gaps.

Note:  The ELO median offset was changed from 2700 to 2800 still anchored with Naum 4.2.  This is an arbitrary change to bring it closer to the ELO ratings with other chess engines rating sites and probably also closer to the ratings of FIDE.
