Back to the cursed DADA-job

Wondering just how cursed this job really is, or if JK made a mistake 
with the teacher-last-only-one-year vs Quirrell.

It seems to me, Quirrell would have taught DADA for more than just 1 
year - but maybe I've read the actual curse wrong.

If in fact the curse starts over each year, then obviously Quirrell 
must have been teaching just one year - but several things point to 
the opposite.

Sorry, I don't have the books handy right now - but Percy tells Harry 
in PS that "Snape's been after Quirrells job for years", which 
indicates that Quirrell has been actually teaching the job for years - 
but of course could also refer to the point that Snape's been 
after "the job Quirrell holds at the moment" for years.

Another dialogue pointing to Quirrell teaching DADA for more than a 
single year, is in OOTP when Harry speaks to Fred and George about 
previous DADA-teachers - and they (or one of them, dont remember 
which) refer to the 4 previous DADA-teachers who didn't last long - 
referring to Quirrell, Lockhart, Lupin and Moody.
But Fred and George had been at Hogwarts 2 years before Harry came 
along, so why refer to only these 4 and not mention who was DADA-
teacher right before Quirrell, since if there was a different one 
right before him, Fred & George would have had him/her as DADA-teacher.

So maybe I got the one-year-thing all wrong and not even sure it says 
so in HBP, that no teacher ever lasted more than one year - but by 
weak memory I seem to remember Dumbledore actually telling Harry 
that's how the curse works. 
Someone with the books closer by will definitely clear that up for 
me :)
