One of the Q proofs for SOH has to do with the Q delta post 497:

Good[win]
[win]/when
[15]
Q

with the obvious implication that Good played a role in the win during the 15th vote for SOH.

There are counter claims that Good voted "present" and did not actually vote for McCarthy, so is he really relevant to this Q proof?

Lets check with the actual videos:

Good votes for Jordan in the 14th vote

Good votes "present" in the 15th vote

Good changed from opposing McCarthy to voting Present, one amongst 4 in fact, hence changing the balance to the win.

Conclusion: Yes, GOOD did play a crucial role in the final win.
