A "two gun Sam" approach to supplying RRs. Supplies in batches of 200, but has two ILS to do so quickly. This way you don't get thousands of them at once, but you can still get a lot of them very quickly.
Part of the "Fetchingly Fast Furnishment for Blueprint Barons" post and collection. Basic idea is to have a factory that not only makes the things at a good clip, but refills the ILS with replacements super fast to cut down on the wait time when you're slamming down blueprints left and right.
