Casino v1.4 by StupidFatHobbit, upgraded by Konage to guarantee no productivity loss and higher throughput. This is ~10% extra throughput than the "simple" version, particularly for recipes like EM plant. The inserter almost never adds unnecessary ingredients, so when there is a recipe change there are very few ingredients to remove. NOTE: If crafting something with a lot of ingredients (e.g. EM plant, needs 6 stacks per two crafts) you may need to upgrade the requester chest's quality.
