Internet, 80% of Wave's upgrades are through purchases of SEDs? I missed that and am curious where that data came from; not doubting it. I think many here had supposed that, that would be the case. So, if last Q (Q2) there was 6150 upgrades and 15,000 SEDs, 4920 +/- (80% of the upgrades) resulted from SED sales or roughly a 33% attach rate. Have I got that right? Tia
