Hey everyone! I just noticed the discrepancy between what info box says vs how long it actually takes.

The info box in the Foundry shows 10s time to build Metallurgic Science Pack, so I was planning on building 50 of them to have 5/sec, but the factorio calculator showed only 8.4 (I guess calculator parses some lua files to figure out the timings?).

I did some manual timing and it is somewhere around 2.5sec per science pack?

Have you accounted for the productivity bonus ? That wouldn't show in the recipe, but would alter the number of foundries required to produce 5 per second of somethin

Hmmm good question, which upgrade would that be? I only have mining productivity, steel plate productivity and lab research speed so far, plus some simple weapon upgrades.

The foundry itself has an inherent productivity bonus, and you can put productivity modules in it.

Not using any modules or beacons. Shows 50% productivity bonus, which would mean that it would be 6.6sec per item rather than 10sec? Do I understand it correctly?

Both calculators do show 8.4 foundries for 5/sec science packs, which roughly matches what I observe, so I feel like I am really missing something important here

You ignore crafting speed. NaB.

Ooooh I do indeed! Thank you, that solves the mistery! How do I move this topic to "problem between the monitor and the chair" folder?
