IWR6843: Chirp Slop of level sensing demo in Industrial toolbox 4.8

Part Number: IWR6843

Hi experts,

In the file C:\ti\mmwave_industrial_toolbox_4_8_0\labs\level_sensing\68xx_high_accuracy\src\dss\dss_data_path.c, we can see

 frequencySlopeMHzMicoSec =(float)profileCfg.freqSlopeConst * 3600.f* 900.f/((float)(1<<26));  (line 587)

But in the file rl_sensor.h ,  annotation  of profileCfg.freqSlopeConst says 

 For 60GHz devices (57GHz to 64GHz):     

1 LSB = (2.7e6 * 900) / 2^26 = 36.21 kHz/uS  for 60GHz devices , (line 711)

Since 6843 is 60Ghz device,  I think 3600 should be replaced by 2700 to get  frequencySlopeMHzMicoSec.

Can you pls explain why 3600 is used in the codes? 

Customer concern it may lead to the actual chirp slop changed from 33.71Mhz/us to 44.9Mhz/us in the demo.
