Spreading Factor distribution on your gateways?

Hello all,

99% of the time I see SF12 on my gateway. How does this look on your gateways?

these are all non TTN adresses
I’ve seen that too in NL … a lot of watersensors through KPN

Getting the same since our new street lighting system went live in our village… Everything seems hard set to SF12. No ADR implemented.
