Research Lab II appears to consume slightly too much Lab Equipment

Issue description

Research Lab IIs appear to consume slightly more than 4 lab equipment/min, occurring in noticeable spikes in the consumption chart. In gameplay, you may not realize it unless you're running with a very small buffer, as it is on the order of 1-3 extra research parts every 10 or so in-game months.

I might not have noticed it if I hadn't started with a very small reserve and set an empty-storage alarm.

Expected behavior

I expect Research Lab IIs to consume no more than 4 lab equipment/min; making 12 lab equipment/min should keep a trio of Research Lab IIs working indefinitely.

Reproduction steps

Save file attached. Production seems very constant as expected, with every other month being either 8 or 16 items produced, but consumption sometimes spikes above 12/month.

If it helps, I often pause a lot to plan out a new facility.

Game version

v0.4.11

To detail:
Research I consumption spikes from 12 to 15 in a repeating pattern. 12 should be the norm as there is 3 Research Lab IIs.

For context: The issue was that on research completion/change all spent equipment was burned.
