I think this goes a bit too far. There’s no need for super compression, or for compression of minerals.
The 1000:1 and 1mil:1 compression is way too much, and feels more like a fan-made mod from Space Engineers, than it is to be conducive to a functioning economy.
On top of that, efficiency rates for compressing was already lambasted when the changes were announced last year.
I’d recommend taking that scope and paring it down, as per my post above, to limiting Orca and Porp to 10:1 compression on asteroid, merco, and moon ore; keep the current compression mechanics on the rorq, but add in 10:1 moon ore; keep stations at current compression mechanics, but allow further compression of compressed ores from Porp and Orca.
