I know of two typical use cases where archived data makes sense to me. That doesn’t mean there aren’t a lot of others that wouldn’t make sense to the people using them I’m just saying these are the two where I can see having the archive data makes a lot of sense.
First is for people who actually train their bodies for a specific sport. Whether it’s running a marathon, national championship table tennis, or boxing, tuning your body to peak efficiency specific to that sport is a process where you do something for awhile, measure the results, analyze them, and then try something else. So archive data is very valuable. You’re not making on-the-fly adjustments. You’re testing specific techniques over a fairly long period of time.
Second, completely different kind of situation, is for someone who is learning how to manage anxiety through CBT or other procedural approaches. Whether it’s general anxiety, a specific phobia, or PTSD, both heart rate and galvanic skin response are typical laboratory measurements. So if you can take that out into the field, and again do it over a period of time which is then reviewed, in these cases probably with a therapist, that could be very useful data. Just like the marathon runner, we’re looking less for minute by minute adjustments than we are for the effectiveness of one technique vs another (or for improvement in applying one technique) over multiple situations and a relatively long period of time.
There are some other “peak performance” situations where an approach similar to the management of anxiety could be useful, but people tend to be less scientific about those. Pretty much anything that would benefit from meditation practice. For example musical performance, public speaking, a salesperson making cold calls, etc. But again, most people don’t invest the same amount of time and analysis into these as the first two categories.
But while I see a usefulness for archived data, I don’t really see how that would fit into an ST integration, which seems to me more suited to real time events.
