There was one ELR match at the Ashfork location. IIRC the insurance cost was prohibitive because we had a forward observer/spotter protected inside of a large loader bucket. It was still hard for him to spot shots even being another 1000Y in front of the firing point. Really that was the part of the match that became controversial, just trying to see impacts or where the misses went. Well as you can imagine running a ELR match can be much more difficult than a regular match.
The farther steels were 4'x8" sheets placed sideways and vertically. They were from 1800Y to 2356Y I believe, still hard for us to hit in the wind. Also there were some smaller 1-2 moa steels to shoot at a mile and less.
Maybe with video systems or electronic flashers a ELR match would be easier to do. Of course going that route things are going to get costly.
Here's a link to that match.
