Comment (by simonpj):

 > I think this is quite essential to identify beneficial lifts,

 Oh, OK.  If I was reading the paper I'd ask "which bits of this analysis
 really make a difference"?  Eg.

 * If I switched it off altogether, what happens?
 * If I switch off pieces of it, what happens?  We've discussed some of
 these pieces above, but not all, I think.
