Full disclosure - I have known JR since forever, and we used to play every week, until he got that restraining order. But he is still a good friend, and I would gladly accept a kidney from him.
All my games are posted on ROAR. There are scenario designers who have posted, with some justification, that there are not enough playings listed for their scenario to determine if it is truly balanced. So the more of you that add playings, the more accurate the balance will be. This is especially true with the non-MMP scenarios, which tend to have less playings. So support the fringes of ASL by playing and posting results for scenarios from Dispatches From The Bunker, Lone Canuck, LFT, BFP and all the others. (I am still awaiting the next 'On All Fronts' issue...)
I said 'some justification' above, because I remember a post where the designer said that an 11-3 record for his scenario wasn't statistically relevant. I am not a statistician, but after 14 playings, I would expect roughly the same percentages if there were 30, 40, 50 playings.
One friend tends to choose scenarios based on a roughly even ROAR rating. This doesn't always make for a great game. Some have been boring, (Ambush! comes to mind), others might be dependent on the effectiveness of one awesome tank or 1941 Russian OBA.
Another friend tends to look more at the player rating of the scenario, rather than the win/loss record. I can say that I have played a lot of scenarios that were tons of fun, even if not balanced. So if you do post listings, put in your rating for the funness (I make up my own words. Or werds.) of the scenario.
One of the awesome things about ROAR is that it lists all scenarios, even those that some guy posted from his mom's basement while eating a Hot Pocket, and only three people on the planet have seen. It can also be informative to compare the results for a scenario to the results of a reissued, modified version. Sometimes, the newer version is more unbalanced.
Which, coincidentally, is what many people say about me...
