Apologies. Was just a suggestion about how the things kind of correlated.
Only @David.McQuillen.KoS and team will know why 4b/5/6 are all merged together in the app.

And of course we can do whatever analysis we want offline if we want to, especially if HR is the primary or preferred measurement instead of power.
