Tunnel vision loot run? (Shoreline story)

TL:DR - I did a shoreline raid where someone opened all the doors in resort but left a ton of loot behind.

Was doing a shoreline run yesterday. I'm the kind of player that will use up the entire raid clock, extracting with about 5 minutes left, rather than a speed runner. Apparently I came in behind one of these speed runners who was exclusively looking for the red keycard, because it seemed like they looted nothing else.

I spawned in at Road to Customs and head to weather station, which is my normal route for that spawn. I find a Tetriz on top of that server sticking out next to the safe in the weather station building. I hear shooting at Gas station, so I head to East Resort where I find a looted dead scav right at the entrance (entrance closest to rock passage). I know a player is here, but don't hear anything. I head to second floor and check the connection between East and West wing. E205 door is open, still don't hear anything. I check the key cabinet in the hall closet and find the E226 key. I head to E310 and find the door open, but still no noise. I find a bitcoin on the table. Head to second floor to find all the locked doors open, and I find a SherriffEli badge in the cardboard box in E220 or E221, whichever one has the cardboard box in the bathroom. I also find a good deal of other loot in the crates and laying around. Head to admin building, where I find another Tetriz on the bookshelf in the room two doors down from the room that spawns the W216 key. (Someone tell Pestily, his latest shoreline video mentioned a Tetriz spawning on a bookshelf somewhere in admin)

Find all the doors open in the West Wing where I find random loot (bunch of Golden Stars), but still no player.

So out of that raid, I made about 500k roubles off the various loot, and 3 bitcoins after trading in the Tetriz, and a E226 key. A really good run imo, but that's my play style, slow and steady. I guess some people find the get in and out as quick as possible to be fun. I see guides on optimizing profit per run/hour, but I like exploring.

Anyway, thanks for reading. Such a long post, I feel like there should be a reward for getting this far.
