Rem =========================================================================
Rem --> Finally retrieve the best TL, TQ values stored during the sweep
TL_dspfinal = TL_opt
TQ_dspfinal = TQ_opt
At the end, only TL_dspfinal and TQ_dspfinal need to be reprogrammed in the EEPROM.

Rem =============================================================
Rem --> Determine minimizing Cst by calculating average epsilon
epsilon_sum = 0
Cst = 1
For T = T_min To T_max Step T_step
Next
epsilon_mean = (epsilon_sum / n)

Rem =============================================================
Rem --> Determine rms value of epsilons
epsilon_sum = 0
For T = T_min To T_max Step T_step
Next
epsilon_rms = Math.Sqr(epsilon_sum / n)
Rem =============================================================
Rem --> Determine if new optimum parameters were found
If epsilon_rms < epsilon_rms_opt Then
End If
