Better Pedometer - HELP NEEDED!

Have you uploaded 4 separate logs, looks like 2 logs.

yes, should be 4 different logs: 2 walks with two devices each.
I see 4 attachments here, what do you see?

Do you have the step counts recorded by the Bangle as well?

No unfortunatly not. Will do this next time.
But the numbers in harness look reasonalby:
X_STEPS = 6, RAW_THRESHOLD = 14
File, Expected, Simulated, Diff, %, (Original)
210202a-Mi-walk1-b1-accellog2-Mi3=1609.csv, 1609, 1664, 55, 103.42 %, (1113)

Just a quick manual test. Havent understood the auto search yet.

You see that bangle1 (ankle) is closer to Mi3 than bangle2 (wrist) - but its not as clear and stable as I would have expected
