Update

It went terribly.  E hates reading the same thing over and over and refuses to self rate.  He is bored out of his mind and won't even read it to fluency.  He's been reading one line, with complaining, 5-6 times.  He does not achieve fluency level (reading as quickly as speaking).  I figure he would need 10-15 tries to do that and he doesn't want to.

I tried to coax him into giving it a week.  I said it's a method I read about; can't we try it out?  He finds it excruciating.  I don't know if I should stick it out or if I should just try to have him read more.  That, too, isn't going very successfully. 

It may come to him actually not being able at bar mitzva age to read fluently, because he's so vehemently opposed to it.
