ADR lowers SF but then requests multiple transmissions


I’m not sure if what happens with my device is really the best solution. ADR of Chirpstack lowers the SF to 10 but then sets nbRep to 2 and then even 3 as some messages got lost.

I’m just wondering: Is it really better to send a message multiple times instead of just using SF11? In terms of battery life and in terms of air time.
