A screen shot of 199/200:
Here are my setup details.

(1) Hotwire settings (v198), see attached screen snapshot.
This was the last snapshot I did before retiring the RS Pro.
The only thing I varied prior to the last setting was:
-- Boost =>> set from low-ish (around 12) to max (as shown)
-- Drag Brake =>> varied from zero to 33% (as shown)
Note: I do not normally use Drag Brake, it was just a test to see the effect on braking.
(2) Gear = MX3 Radio, EP5200 40C LiPo, HB Cyclone TC, Takeoff or Muchmore Tires, Fan blowing onto motor (but mounted separately to motor).
(3) The MX3 radio is fairly basic. I have varied Throttle and Servo curves, from zero (default, linear straight line) to -55% (more sensitivity down low).
I have re-synced the radio and esc several times to make sure.
(4) In combination with the Boost setting, I have varied motor timing from about 10 degrees advance, to zero (last setting).
(5) I have varied FDR from 4.3 to 5.1 (last setting).
(6) Track = asphalt, outdoors, 1000' foot length, 210' straight, hi-speed into very tight "S" (main problem corner in regards to braking).
(7) I have used the same Tekin 10.5T motor (at zero degrees) with a HW Xerun V2 ESC (at 26 degrees advance) and the braking is quite acceptable.
(8) At lower speeds (say, less than 50% of maximum speed) the braking is ok with the Tekin RS Pro.

Hope this helps.
