One sad fact about shooting raw is the huge number of people with 18-55mm lenses, for example, trying to shoot football games from 200 yards away, or blurry pictures in near darkness of school programs. I've seen countless people who even filled their cards up with a fewer number of raw photos, thinking that was magically making their pictures better, when they would have been better off taking a lot of jpegs and getting lucky on some of them.
Depending on the conditions and type of event, especially if any luck is involved, taking more photos is more critical than getting a few raw frames and filling one's card up.
RAW should be used when there is at least a chance of getting a good photo when pressing the shutter release.
It's a tragedy to me thinking of all the terabytes of raw photos generated when that was not the case.
RAW can't do miracles.
