Training in house with a certain level collects mats faster, with some collect from a prod set and a little from a robot you hit the max without collect cards.
Server base-collect & facture speed is like 40%.
If you use cards it'll reduce the time on the facturing but if you look closely it'll count down and back up and will be off by a good margin...
thanks everyone for the responses. it seems the fastest way would be just using cards constantly and maximizing my time. Although I am already doing that, it still feels way too slow.
And getting to the level of a house required for collecting? I'm too poor for that LOL
