It's odd how this duelling ladder business is deemed to be a yardstick of "skill", when those who express that POV would, in the same breath, proclaim that "rank does not mean a thing" in the MA.
Being good in a duelling ladder means one thing - you're good at the particular game (and version of said game) that is the subject of said duelling ladder. You've learned all the nuances and gamey tricks there are to know, and you've fine tuned your stick settings to the nth degree to suit a particular plane in a particular
game.
But does it mean anything else? Probably not. In my tenure in flightsimdom, I have fought against RL fighter pilots, and was surprised to discover that at the height of my game (1999/2000) I could beat one or two of them quite easily. The main reason is probably that these games are good simulations, but come nowhere close to an RL flying experience.
It's somewhat anomalous to look at that ladder and see that one guy who shone in AH1 could not hack AH2 and deleted his account. Another has recently retired from AH2, but in another thread expresses a desire to continue privately with AH1. Hmmm - why would that be then?
Psst - the flight model and gunnery model in AH1 were flawed - that's why they brought out AH2 - more power to their elbow...Of course, some might try the duelling ladders as a way of having fun, and there can be no denying the ego stroking properties of such an enterprise, these perhaps being the principal reason for why some of the participants are there in the first place.
But I would no more participate in a duelling ladder to discover who was "best", any more than I would pour ££££ into the "Golden Tee" video golf game at my local pub, get my initials to the top of the rankings, and then crow to Tiger Woods about how good I was at video golf.
