Description
Each Half Belt of Science can support approximately 32 Biolabs at 60 second science research (double that for Research Productivity, at 120 second, and half that for Robot Follower Count, at 30 second), for a grand total of 28K SPM at 0 Research Productivity, but all Legendary Tier 3 Productivity Modules.
1 M SPM = 37 "blocks" of 32 biolabs apiece, each with half belt sources of science, consuming ~265K packs per MINUTE (Gleba obviously requires more due to spoilage, too).
