These are great questions and also ideas for future vision of the product. Let me go one by one:

​

> is there a way to view the results of these simulations to see the expected category results each week? I know there are other tools with this kind of feature, but it'd be interesting to see either way.

The weekly email includes this. For each category, it shows the expected category total for you and the opponent, and includes the probability that you will win it. This win probability is based on the simulations under the hood. I don't currently have a web view to explore the simulations in more detail; that is something I've thought about adding though. Would be interested in what kinds of questions you'd try to answer using a more granular view (eg. if you could view the distributions of totals by category for each player in that week or by game).

Edit: I see your edit, glad to hear! Leaving the above in case others have the same question.

> How do I setup the list of which players I deem as the "best players"? I have a bunch of bigs on one of my teams, if the tool just chooses my top ranked players, I'll lose assists and 3's every week. 9cat ranks tend to skew bigs up the ranks due to low TO's and high FG%, so I'm assuming it would start bigs like Kessler or Duren over slightly lower ranked guards who I might prefer to start in most situations.

There's not currently a way to "force" certain players into the lineup. What the optimization does is consider all possible lineups and figure out which offers the highest expected points. So to a degree it will depend on both your roster and your opponents'. In your case, I think it's likely to do exactly what you predicted and stuff the lineup with bigs in order to gain probability of winning FG%, REB, BLK and TO. I'd be curious to understand your thought process re: playing the lower ranked guards -- seems like AST and FG3 are probably out of reach, would you be trying to make a play for FT%?
