I believe that the axis won 7 or 8 of the 10 or 11 G42 games played (perhaps all without a bid), so your conclusion is shared by many…but not myself.
The victory condition and tournament time meant that many people stipulated or played to exactly 7 turns (unless opponents conceded the victory). This predictable end creates some gamey outcomes that would not exactly be featured in an completely open G42 game. People send in everything to die in one last ditch effort to stop or achieve Economic Victory. Buys on the last turn are not game-affecting for several teams.
That would lead to a question, is it “tournament” balanced, or “generally” balanced. The G42 scenario comes to a certain head around turn 7-8 (when the KJF/KIF/KGF is in full swing)
but several things I said “would never happen” such as seeing Moscow (x1) London (x2) Japan (x1) or Sydney (x1) fall in this tournament, did come true 6 times!
