R5: using stairs (a lot) it's possible to descend 20-25 floors in one in game hour and then carpet bomb the place for loot (iridium ores, mostly).

I usually do this for floor 50-80 but then I got bored and tempted "what about floor 300+?"

There isn't a substantial difference between floor 50 and floor 300 in terms of iridium ores. There is 2 chests in floor 200, and 3 in floor 300, but you might probably get junk.

So i think, it's better to switch the jade into diamond in crystalarium, less micromanagement. Unless you really want the auto-petter hehe.
