percentage error op-amp

[stealthelectric]

Hi:
I am trying to calculate the percentage error for an inverting and non-inverting op-amp.
For the inverting op-amp the error is 0.7V. This is the difference between the theoretical gain -Rf/Rin=100k/10k=10, and measured gain Vout/Vin=16.6/0.2=9.3

error is 0.7V.
Percentage error = 18.6/2 =9.3
0.7/18.6x100=3.8%
0.7/2x100=35%
3.8%+35%=38.8%
0.338x9.3=3.1V
For the non-inverting op-amp the error is 0.1V.
Percentage error = 3.80/2 =1.9
0.1/3.8x100=0.03%
0.1/2x100=0.05%
0.03%+0.05%=0.08%
0.0008x1.9=0.0015V

Have I done this right?

thank you
