There are a lot of tidbits in this game that create micro advantages and most of these in themselves aren’t hard to execute.
For example you can have villagers drop off resources gathered at ANY depot, if you task said villagers to build the drop-off depot.
Another tidbit, building any structure with 1 villager is the most efficient in terms resources gathering opportunities.
Now let’s combined the top 2 concepts above into an actual scenario.
The common delhi opener macro is to send 5 of your starting 6 villagers to a straggler tree nearest your berries then send the 6th villager to lay down the mill blueprint. Once the 5 villagers have each gathered 10 wood, instead of them going to the Towncenter to drop off the wood, you task the 5 to complete building the mill!! Once the mill is complete the villagers will drop off their wood then go to foraging the berries.
But let’s go a little further in our analysis of what was just described and what opportunities we gained/missed.
Straggler trees are typically 2 tiles from the Towncenter,
and walk speed for a villager is 1.125 tiles per second. So NOT having the villagers walk BACK to the TC THEN to the mill saves you 4 tiles of walking which equates to, ( 4 tiles / 1.125 tiles per second ) × 5 villagers = 17.78 Villager-seconds!!
Note: Villager-seconds is a contrived unit that helps illustrate potential for work done. It’s quite literally 1 villager active for 1 second. But it can also be linearly representative of several villagers being active for fractions of a second. Its most direct use is to multiply it by an effective gathering rate and get a sense of resources you would have obtained. So take the 17.78 V-s and multiply by an effective gathering rate of 0.66 resources per second and get 'bout 11.7 resources. Another way to stating the above equation is to say: those 5 villagers NOT having to walk those unnecessary 4 tiles garnered you an extra 11.7 resources assuming an effective gathering rate of 0.66 resources per second.
But remember i mentioned the most resources gathering efficient ( aka minimum Villager-seconds) way to build any structure is with a single villager?
So what is the minimum Villager-seconds to build a mill? The minimum is only achieved by using 1 villager so by definition the moment you use more than one you start to lose more villager seconds!! Well in the scenario above you just cut out walking 4 tiles which garnered you 17+ V-s, the question becomes are you going to forfeit those saving by using more than 1 villager to complete the mill???
Let’s do th math. The formula for calculating build time of a structure is base_build_time × (3/[Villager-buiders + 2]). This formula works for all structure and all NON chinese and ootd villagers. One villager takes 20s to build a mill ( 20 × ( 3/[1 + 2]) = 20s ). 1 villager was active for 20s therefore expended 20 V-s. Meanwhile 5 villagers build a mill in 8.57s ( 20 × ( 3/[5 + 2]) = 8.57s). But that’s 5 villagers active for 8.57s which equals 42.85 V-s…Hmmmmmm. To b clear YOU NEED the mill so building it is unavoidable; this means at minimum 20V-s MUST be expended, period. But with 5 villagers you expended an EXCESS of 22.85 Vil-s?!! You not only negated the +17 V-s from before but choosing to build the mill from scratch with the 5 villagers resulted you a net NEGATIVE villagers seconds gained?? And to make matters worse you STILL didn’t build the mill the fastest possible because you could have had it up sooner by having the single villager build it up immediately… in other words… THERE ARE NO ADVANTAGES TO WHAT YOU JUST DID.
I need you all to vet this thru, because i watch a lot of replays and even the pros can be caught making this MISTAKE thinking they are gaining an advantage.
What you SHOULD DO to retain as much of your gained Villager-seconds by NOT walking those 4 tiles to the TC and back is to have the original mill villager build the mill all the way to a moment before completion. Then have the 5 straggler tree villagers tap the mil to completion.
CRUDE WHOLE NUMBER MATH:
Original mill villager spends 20s to start the mill BUT leaves it incomplete, THEN the 5 straggler tree villagers avoid walking back to the TC takes their payload to the incomplete mill to tap the mill to completion which take 1 WHOLE SECOND… The total Villager-seconds expended on building that mill would be 20V-s (from the first vil) + 5V-s ( from the 5 villagers active for 1 second) for a total of 25 V-s. Since 20 V-s is unavoidable, it means you’re only negative 5 V-s from the mill yet +17 V-s from avoiding the 4 tiles roundtrip for a net GAIN of +12 V-s!
