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.
I agree, planning of this degree is quite impressive. It is the bread and butter of Military Staff work. It doesn't always work out as planned but there are always contingency plans to attempt to foresee all potential obstacles.
We will probably never know the complete history of this operation, due to continuing operational security. A lot of this information has to be kept secret in case certain tactics and methods are required in future.
