I think all have touched on good points, but it has come to a pissing match. The original question was basically how can the new shooters learn more from matches.
Watch the guys that are winning matches. This includes youtube videos, local matches, etc. Go up and ask questions after the match is over or at breaks. Everyone is in this sport to help out really. Having shot with some of the best in the nation as well as being good friends with alot of them, they are all willing to help out and give suggestions. Listen to what they have to say on technique, equipment, etc, but don't bug them so much it becomes a hinderance to their own shooting.
The biggest thing is just get out and shoot. Whether is 100yds or 1000yds, their is no substitute for trigger time. Practice from barricades or natural barricades. I realize its difficult for some to shoot anywhere other than a range, so they will need some props. If you can get out into the field and use "natural" props, it will help out even more. Most matches are just that, FIELD matches with natural terrain, not a groomed range. Train how you are going to use the training.
Push yourself until you start falling off on the accuracy, and then back off a little. Speed will come, but accuracy is where everyone should focus on first. There are 2 things I see new guys trying to do that hurt them. The first is speed. They try to go so fast that they are missing hits and getting discouraged.....SLOW DOWN. This is precision rifle, not 3 gun. The second is the equipment race. All the latest gear is great, but an accurate rifle is the most important. Jesse and I won most of the matches we shot in the early days using our BDL coyote rifles with Duplex reticles. This included multiple Findlay Cup, Idaho State Sniper Challenge, and others. The main reason, we knew the guns and they are accurate.
Shooting ELR is fun, but it takes more equipment than most want to dive into. Considering that 90% of matches the bulk of the targets are in the 300-700 range and beginning to be more positional, the practice we do at UN is perfect. Match directors are realizing that its pretty easy to hit stuff prone, no matter what the distance. So what do we do, either make the targets smaller, add a short time, or something positional. This is all the stuff we need to practice.
Hopefully this all makes sense.
