Obviously I'm a bit biased, but I can say with confidence that the vast majority of our live drafts run smoothly. When they don't, I hear about it, so I'd know
Another tip I can give is using your queue while in the live draft room. Any players you put into the queue during the draft are stored server-side, so that can come in handy as well if your ISP burps and you're disconnected. Look at it like this: your pre-ranks basically re-order how we rank players relative to each other, but the autopick algorithm doesn't always pick the highest ranked player (or you might end up with 5 quarterbacks or something). If the autopicker intends to pick you a quarterback, your pre-ranks can definitely impact which one you get. Now your queue is a different matter. The queue says, "This is who I want. End of story." So if nothing else, if you know who you want to pick next, and you put them in your queue, even if you get disconnected due to network problems, then as long as that person is still available, that's who you will pick. Make sense?
