The following forum is related to SRM PC8 and associated firmware development.
Yes. SRM says
"If the PC8 would cause this issue, we would have Power Spikes with all systems transmitting read calculated Power. ... Its more likely that something is rolling over in the DA PowerMeter at a continuous interval, but I could only tell for sure if I could examine the ANT+ Data that is transmitted by the PowerMeter. The PC8 does not do any filtering of the received data, because its ready calculated and should be correct."
Shimano asked me to update R9100-P firmware, which I did, to no improvement.
I am still investigating and soon will be trying different equipment parings (eg PC8/power2Max, Wahoo Bolt/R9100-P, E-TUBE app/R9100-P).
Thanks. Keep up the good work
