Sharing set up files is nice. Its fantastic in fact. You can check out a whole slew of someone's changes with one button press. However its also annoying as hell to decipher if you want to figure out the logic of something that somebody has done. How can I tell the difference between somebody who changes his set up intelligently, progressively, and in response to previous changes and somebody who just clicks randomly? I know many just want to find a better set up, drop it in, and be done with it. That'll always be there for you, but for the rest of you who know wtf you're talking about please... I'm begging you, describe your changes. Its kind of the old give a man a fish, teach a man to fish thing. If you just drop the file here nobody learns anything except through laborious examination of changes, then driving, and not being able to be sure how every change adds up is so time consuming its hard to learn quickly and we're not benefiting from one another's education, not in the sense of learning anything, all we get instead is a file. Those who describe the changes they made, the results of those changes, the reasons they made the changes, and how those changes affect other characteristics of the car and the changes that need to be made to balance those results out AND how that makes sense in the context of the track are so much more valuable to me than a file. So, just like... a few words to go with the set up file, like... 5% of what I've written here will do. TL: DR - Sharing set up changes isn't as useful as explaining set up changes. Cheers.
