The attached excel sheet helps to estimate a practical range estimation for indoor and outdoor radio links.
The outdoor is based upon Line-of-Sight (LOS). For the indoor estimation, construction materials can be selected that are between the Tx and Rx unit. The greater the attenuation of the combined material between the Tx and Rx unit, the shorter the distance.
This has been used a lot in TI seminars and is a helpful tool for calculating a realistic and conservative range expectation.

What value should be used for an 80% efficient antenna in your spread sheet?
-1 dB fixed Gain?
2 launchpads, LAUNCHXL-CC2640R2, activated on 2 separate laptops, using Smart RF Studio.Everything at default settings: Tx power at 5dB, CH 17, PDU length 30, One device on continuous Tx, the other on Rx. At 1mega-symbol/sec, indoor range is about ~12m (both 0.125m/s and 1.0m/s at 9% error rate) At 0.125mega-symbol/sec, indoor range is about ~14m (70% error rate at 0.125m/s, no reception at all at 1.0m/s). I might have done something wrong to give such a short range, but even so, the RATIO between the distances should have been 2 (+6dB, meaning 2x range)
-1dB corresponds to 80% efficient antenna.

Thank you for assisting:
What do you mean by "50kbps default setting"? The default in most (all?) BLE demo projects is 1mbps. or is it? I didn't even know there was a 50kbps option under the BLE protocol. I thought the lowest is 125kbps, with coded-8 mode.
Is there a specific demo project you suggest I run? Or should I test both LP's using Smart RF Studio? (I haven't seen a 50kbps option under Studio, but maybe I've missed it).
