I agree that the operations of Pitcher settings should be part the basic instructions on here, since they are vital to having success on this game.
Unfortunately, there's not a ton of official guidance on here, and many of the veterans who have figured out the nuances over the years like to be the keeper(s) of that uncommon knowledge and dole it out condescendingly to newer players. Others give out it more freely but still expect you to show great deference to their superior intelligence (which is actually just superior knowledge, but they don't undertsand the difference). Not all veterans, of course, some are very helpful, but there's one or two on this thread for sure.
Generally you'll get the anwers you're looking for, you'll just have to wade through some douchiness to get it. But if you're in a league with good owners, sometime you can get better feedback by posting there.
