Hi John,
nobody is against moving to spec06. It is the quite heavily approximated
conversion factor of 4 that leaves me personally without words and the
fact that that is considered more accurate than an educated guess on an
architecture. Manchester got the numbers from DELL and they are
consistent with the WLCG table and we have 4.44, Sheffield has 4.5.
Today I'll go through Lancaster and Liverpool.
