I note that in the Gaylord/Dorsey announcement NRGY stated that they served 245000 retail customers. In the announcement today they stated that they serve 260000. So that's a 6% increase in their retail base since the 01mar Direct Propane announcement.
That's 85% annualized! :) Of course, it looks like they don't try to keep the number of retail customers they serve up to date in each press release. I notice it held at 245k through the Pembroke, Gaylord, and Direct announcements. Those three must have added at least 5k.
