The bush I'm beating about here is (and, again, this is just an example) to separate the effects of:
JP's perception that 7-8 is the worst payer (therefore lay off)
(actually, my data indicate
that too many people actually back the 7-8 because it's the BIGGEST payer,
despite the fact that frequency of finish numbers don't overcome that)
vs.
I don't care if it's 7-8, 'cause it's Goiko/Rekalde (lay on)
Both are at work here, perhaps a wash.
