RE: Error rate and Luck adjusted result

[Ian Shaw]

Hi Franceso.

Error rates are "normalised". That is,  they are adjusted to make them all 
match the size that the error would be if you were playing a money game and  
the cube were at 1. 

Luck takes into account the match score. For example, a lucky 66 makes a much 
bigger difference to the overall result of the match if comes in a bearoff at 
double match point rather in game 1 of an 11 pointer. 

Cheers,
Ian

Subject: Error rate and Luck adjusted result

Why are (sometimes) Error rate and Luck adjusted result discordant?

I try analyse every match I play. Now and then The Error rate stat and the Luck 
adjusted result are discordant: that is, one player seems to have performed 
better — sometimes, way better — in one stat and worse — sometimes, way worse — 
on the other.

I understand these are two different calculations and cannot be compared with 
simple algebra. Can someone come up with a simple example where why Error rate 
is lower than my opponent but the Luck adjusted result is in his favour?

Thanks and happy rolls
