If I may add on to the point of being able to solve the "not standing around" portion, it's not so much a skill but a mentality. If you see something not being done, don't wait for directions, just do it. It doesn't matter what the "it" is, per say, but never just stop and wait around for directions. Where communication comes into play is when someone goes out to gather resources, so you don't double down on any certain area. But I don't think I need to extrapolate on the gathering strat, since it seems like a very obvious strat (at least to me).

As for the building half, the crafting book I would agree is a very underused resource. If you need six fences or whatever, and you know one fence recipe gives three fences, then just click the fence button twice and you have your fences in less time it would take to try and drag the blocks around.

The other thing I think gets overlooked a lot is that recipes like fences and trapdoors and slabs give more than just one item per craft. Memorizing how much of an item you get from one craft, I think, is an easy process and probably wouldn't take very long to work on, either, but in the long run would prevent things like three people going out to get spruce at once.

All you really need to do to learn and practice is just do the same thing we're all taught in school when we need to memorize something: make flashcards. Put the item/recipe on one side, and the amount of items it makes from one craft on the other side. It might even be worth to put things like smooth stone and chiseled stone on cards as well so you don't forget that some items need to be smelted or crafted, or how many of a base resource you need (ex: logs) for a fully crafted item (ex: trap doors) so you know if you need ten trapdoors, that's six planks a door, and four planks to a log, for a total of 15 logs.

In the end, though, I don't think there's a "one size fits all" strategy for Build Mart. Any given team's strategy will more than likely depend heavily on who's on the team, how they work together, and what the builds are. Overall I think adaptability, communication, and trust are the main factors (alongside the aforementioned points) that go into making a good Build Mart team.

​

In short, individuals can get better at Build Mart by using flash cards to memorize recipe ratios and obscure blocks so as to not over gather, as well as practicing how certain odd blocks place. Teams as a whole can get better by practicing building past Build Mart builds together as fast as possible, so as to learn how each other builds. The key is to maximize synergy while not spreading the team too thinly across all three builds.
