Power level min/max the same number?

I recently saw the power was set 20 for the minimum and maximum. Why would this be? Isn't this essentially disabling RRM by forcing all APs to transmit at the same power level?

Transmit Power Range

Using this option, customers can set a custom range for the TX power. Although, AutoTX Power tries to optimize the TX power based on the overall RF environment. In complex environments, it may be necessary to limit the range depending on the requirements.

Transmit power range will be set to 5 - 30 dBm for 2.4 GHz and 8 - 30 dBm for 5 GHz if Enable Automatic power reduction is selected on the old radio settings page. If Always use 100% power is selected transmit power range will be set to 30 dBm for both bands. If any APs have TX power and channel set manually, the settings will be retained and the AP will be counted towards one of the APs that have overrides. Rx-SOP will be set to a default value of -95 dBm.

Yes if you make the slider only one slot you will effectively put the desired Tx Power on that level.

However you do have the regulatory limitations so chances are high the AP will transmit at a lower power which is max allowed EIRP minus antenna gain (rounded up to next integer).

This can be a design choice if you surveyed your environment at for example 14 dBm TxPower that you put all sliders on 14 dBm. If you designed for enough secondary AP coverage then an AP coverage should not really impact the coverage performance.
