I actually thought Judau was one of the more "realistic" main characters in terms of piloting.

Amuro and Kamille (hell, even Uso) were taking out or at least matching some aces even early on in their respective series with what limited knowledge they had of things (Kamille with slightly more than Amuro), but Judau's early victories were more or less flukes and pure luck even though he DID, presumably, have more knowledge on MS in general from the get-go. (Being a Junk Dealer, he probably saw his fair share of busted MS that he could've looked at while also piloting middle-size MS for collecting and all.)

Not to mention making basic mistakes like forgetting to have the Zeta's beam rifle charged up before going into battle and such, lol.

He gained experience through his various battles against various Neo Zeon pilots, including dangerous ones like Puru and Puru Two which would help explain why he was able to fight so well against Haman. And considering Haman didn't really do much besides sit on the Command Ships and shout orders throughout ZZ, well, that'd cause anyone's skills to dull, if only slightly. We also can't forget that, compared to the Zeta Gundam in general, the ZZ is a BIG step up in each area of general performance while Haman is still using just the normal Qubeley. Sometimes MS performance CAN make up for difference in piloting skill. Amuro shows us that with the Gundam in MSG after all. Not to mention Judau has his own experience from fighting (slightly better) Qubeley's with Puru and Puru Two. Fighting even MORE powerful MS like the Psyco Gundam Mark II and the Quin Mantha and others would help too.




...and for the age difference thing...Uso and most of the Shrike Team? XD
