well what uysually happens with loads of releases on record catalogues is that the label sets out to release stuff from say 001 to 010...in the first instance.
it then assigns numbers to specific releases, perhaps well in advance of them being actually ready...or even leaves a specific number out because its for a special release....
Underwater records are a good case in point for this:
Emerson the owner of the label sidelined release H2O 050 for his own track, which didn't come out until after later releases such as 052, 054 & 057
and they are currently up to release H2O 073 in terms of numbers but there have not been 064 or 065 released yet...
its simple cataloging which Tony Wilson at Factory records was a genius at, and it may be something similar with Underworld (and their new? label) or may in fact be nothing...
i think you kinda need three releases for it to statistically be a trend...lets wait 'n' see
