By no means a slave to it; but I'm obsessed to the extent that I get angry when I discover that it failed to record something, like when I didn't capture my Citibike ride to a meeting yesterday morning. Yes I try to capture everything, and manually enter conservative estimates for rides it misses, and I manually enter rollers sessions (all logged under rollers, not under bike used). The mapping and performance comparison aspect is just one side of it. The other side is what I get from Velo Viewer, which for me is all about history and patterns, and only as valuable as it is complete.
