@Patricia Davis good question — the MultiNav Pro+ doesn't do automatic TX power scaling out of the box. It's designed to hit those extreme range figures, so the default config is optimized for maximum output, not adaptive power control.
That said, if your closer nodes are running off the Power/Program Kit or any battery-constrained setup, you'd want to look at managing TX power manually through firmware. The AI Firmware Builder in the Dev Hub is actually pretty useful for this kind of thing — describe your use case (mixed short/long range nodes, asset tracking, power budget) and it'll generate a starting point you can tune from.
For 10-50m nodes blasting at full power you're not going to damage anything, but you're burning unnecessary current and potentially saturating the receiver on the close end — worth reining in if battery life matters to your deployment.
