But if we look at the full figures Albert quoted:
Overall statistics
Error rate (total) -2.769 (-29.273%) -1.134 (-14.183%)
Error rate (per decision) -51.28 ( -0.542%) -20.25 ( -0.253%)
Equiv. Snowie error rate -26.37 -10.80
Overall rating Awful! Casual player
Actual result +50.00% -50.00%
Luck adjusted result -11.78% +11.78%
Luck based FIBS rating diff. -186.55
Error based abs. FIBS rating 1465.2 1704.0
Chequerplay errors rating loss 353.5 344.7
Cube errors rating loss 231.4 1.3
The left hand column has an overall error rate of .020
The Cube errors rating loss is 1.3, chequer play is 344.7, which
suggests very strongly that cube errors were not a factor here, and
that the overall error rate comes from chequer errors. The Fibs rating
is 1700.
Colour me surprised.
I have noticed similar estimated ratings vs. chequer play error rates in my own
games (unlike Albert, Intermediate is about all I achieve with any
regularity. And, for a laugh, here's a 7 point match I played far too late at
night with embarassingly bad play, in fact, simply appalling play:

Now you're telling me that an average chequer play error of .023, an average
cube error of .13 an overall error rate of .020 is 1750 level play on FIBs?
I find that difficult to credit.
