Connect Improperly Sending 'Walking + Running Distance' to Health

Any particular reason why it would be expected to not sync just a total ? If your argument is that the internal accelerometer does that, I'd notice that having to enter this data continuously is more heavy on battery consumption, then the phone doing it internally.

Phone:

- measures data on a dedicated hardware chip, saving to Health is instant

Garmin Connect:

- has to wake the phone
- uses BT connection
- BT is slow for data transfer, so the radio used for data isn't instant
- has to repeat this in intervals.

I mean ideally you'd have the data at the same intervals then iPhone sensor saves it, but it would take a big hit on the battery.

Because that's what it does for Steps and if the "Running + Walking Distance" is just a calculation of steps x stride length, then there's no reason not to incrementally update that value in similar way to Steps.

See above. Its own app does it properly for Steps, just want the other value to update in same way.

I've already shown it doesn't do that (Steps only increment every hour - iPhone is real-time), so not expecting that.
