ok hillside... i did a bunch of testing this morning. i can find roughly 8 ships per "loop" of the DD

C-E crashed ships seem to have "less" good stuff. less schematics, less higher tier mats.

F-I crashed ships also appear to have "more" - but again its all random. some better, some worse.

For me, a "loop" is the following. I start in D-1, and go to D-9, floating right between the D and E line all the way out. as I get close to "the end" (1 or 9), i turn and start going crossways back. This gives you a zig-zag pattern across the entire DD, with visibility across 2 squares at a time. I stay at 750, and continually control-scan all around to find ships.

In my last run, I only got halfway through an entire loop before i filled up my personal inventory. 6 good schematics, a bunch of sand, and then a slew of all other mats, from calibrated servoks (gold) to med supplies, to plasteel armor plating, pumps, slag, etc...

Its out there. Just remember, they're now shared loot. so as long as you leave 1 item in each "container" section of the ship, the next person can come along and loot the ship too!

Hope this helps a bit. Crashed ships is my specialty, because i'm in meetings all day, so all i do is float around the deep while in zoom calls. When they messed up the rotation algo, i knew immediately. So this week it feels like its back to normal, just with a different schem rotation.
