The Math Just Does Not Quite Compute

How is this possible?

For those that cannot make it out black obtained an 88.5 Accuracy score with 9 inaccuracies in a 35 move game.  Percentage wise that comes out to 26%.  And never mind black's 2 blunders! 

Obviously Accuracy score is not actually meant to be expressed as a true percentage but with basically 11 poor moves out of 35 (31%) how can the score be so high?  And by the way white's numbers do not compute so well either.

The percentages make no sense here either.

No transparency in how they're calculated.

Somebody told me when the first person makes an error, it goes easy on the original person, not quite sure either way don't trust the computer

Might be based off another algo. Different moves and positions will therefore impact how much each bad move actually impacts the percentage.

And your example is almost a year old.  So obviously not much has changed.
