Game variant with greatest player error?

[tech58]

Thanks, TripleTriple for your viewpoint.
I play 9/6 JOB 99% of the time. At home i use a trainer mode to flag errors. 99% of my errors are in the area on the strategy card where ER difference is 00Nats..t (a technical term from my Ind. Eng. days for a very small #).
But once in a while i miss a small pair and discard 5, which may double my error rate of 3 or 4 previous misses.
To paraphrase what i think you were saying : There are errors and there are ERRORS.
