Suggestion: Break down corpses faster cumulatively..

[Gantros]

Since resources like alloys and crystals can be hard to come by, and rendering/dismantling corpses is usually time better spent doing other research, how aobut making it so that each time you render a corpse, repeating it (for type) takes less time, thematically explained as your scientists get better at breaking down the bodies as they get more experience. Eventually, it could be 1 day or even instant.
