I'm not sure why I would care to defend him, but it seems that his claim that the data is not real time can be verified by the first image in the parent comment's list. In that shot there's a column listing the 'Upload Reason'. The reasons include "Scheduled" and "Archive full", which seems to indicate that the software reports back at set times unless the user was particularly active and the data file hit some size limit.

There's also a third upload reason in that image which has it's own disturbing implications: "SMS_PullRequest_CS".
