I hate beating this drum, but feel that three runs with the rubber sleeve proves the point to my own satisfaction (once is nothing, twice could be a fluke, thrice removes doubt). Also, today the temperature dropped enough for me to switch from T-shirt to a long-sleeved top - still 100% polyester - which would provide even more surface for electrostatic generation against the windbreaking jacket. The result was not as squeaky clean an R-R graph as from the previous session, but the Runalyze fault numbers are in line with the great ones from session one and two:
Anomalies: 0.0%
Artifacts: 0.2%

And, once again, the R-R zigzag at the beginning mirror a real HR drop from 108 bpm to 101 - confirmed by the OHR FR955 control watch.
This posting also gives me an opportunity for a piece of advice: Check the SHRM2 connectivity before stepping outside for an exercise!
When I stood in the middle of the village and discovered that the pod hadn’t been automatically activated by putting the (wet) strap on my chest, I didn’t feel like stripping down for pod examination. Home again it turned out that neither looking at the registered HR device listing, nor going into an activity, would wake the pod up. A quick press of the pod button did nothing (and the LED didn’t light up). A slightly longer press did nothing. Finally with a perhaps 3 seconds long press of the button both the LED lit up and the watch could make a connection.
Perhaps there is a hard shutdown timer in the SHRM2; it had been more than 48 hours since the previous exercise. Or perhaps my touching the outer shell at various points with the leads of a multimeter had triggered an emergency shutdown - I was looking for the beeping tone of a zero resistance area, and found none.
This episode also revealed a disadvantage of using a rubber tube. It prevents easy access to the pod button…
