Aion FX Theseus - Incorrect Voltages on IC2

I have built my first pedal, an Aion FX Theseus in kit form (docs -> https://aionfx.com/app/files/docs/theseus_kit_documentation.pdf).

I am getting sound out of both sides, but when checking to make sure I really did get _everything_ right I checked the voltage readings against those on page 30 of the docs and found an anomaly.

The reference voltages (from the docs) are from a 9.6V supply:
  IC1                          IC2
Pin Voltage                  Pin Voltage
1     4.66                    1    4.64
2     4.67                    2    4.64
3     4.25                    3    4.22
4     0.00                    4    0.00
5     4.57                    5    4.54
6     4.57                    6    4.54
7     4.56                    7    4.53
8     9.15                    8    9.15

And my voltages from a 9.4V supply are:
  IC1                          IC2
Pin Voltage                  Pin Voltage
1     4.56                    1    4.47
2     4.57                    2    4.50
3     4.19                    3    4.48
4     0.00                    4    0.00
5     4.48                    5    4.12
6     4.50                    6    4.58
7     4.47                    7    4.56
8     8.97                    8    8.98

From the above it would seem that the voltage on my IC2 pin 5 should be at pin 3 (schematic is on page 28 of the docs if that helps).

After searching I could not find a similar issue, so asking here in the hope that someone might know what I've done wrong.

Many thanks in advance.

Looks fine to me. If the pedal is working properly, the voltage differences could be attributed to differences in part tolerances, difference in voltage, etc. We are talking less than 1/2 of a volt  :)

Rock on!

Thank you for confirming that all is well!  And Happy New Year!!
