The OPAL_2004 paper for example refers to "91.0-91.5 GeV" with a mean of
91.3, but those were late runs (1996-2000) and small integrated
luminosity. There was also the "1993 energy scan" running at peak-2 and
peak+2 (in fact +- 1.790 GeV), and some other runs around the peak.
Nevertheless, the main runs that made it into the large QCD papers were
at 91.2, and that's what you also find quoted in e.g. the ALEPH_1996 or
the OPAL_1998 paper.

Cheers,

    Hendrik
