Well, lately I've been researching the production time efficiency of some of my blueprints to basically get a higher turnover on my production. Right now I've got several blueprints where the research has shaved FIVE HOURS per complete run off of the total production time.
That's fugging huge.
Five hours faster turnaround is five hours more I can use producing more items. It's also five hours worth of installation rental I don't have to pay on inefficient production.
One of the skills I'm working on is production efficiency, so that less of the materials I harvest or buy get wasted. Higher profit there.
