Calculation of control to output transfer function

EXPLANATION

Picture 1 is control to output transfer function. (For those wondering how I obtained this formula, you can check Control to output transfer function. This formula was obtained with the help of VerbalKint.)

Picture 2 is my calculations about pole, dc gain, zero and phase.

Picture 3 is the LTspice simulation.

Note: Question is very easy to follow for those who knows the calculation of transfer function.

QUESTION

The LTspice calculation seems correct but I have mistakes in handmade calculation.

  • As seen in my calculation, Q value is 1.033x10^-5, which is -99.71 dB. Why does Q have such a strange value?
  • I found the phase asymptote values ​​for quadratic pole as 0 degrees and 10^48402, which is infinite. I cannot find the correct phase break points, where am I making a mistake?
  • It seems the the phase of zero starts at 340 Hz and ends at 34 kHz. It doesn't match with the LTspice result.

So basically what is wrong with my calculation?
