At 2 SCVs/mineral and 3 SCVs/gas, a base with 8 minerals and 2 gas will harvest ~672 minerals and ~215 gas per game minute.
thats 42 minerals per worker per min
and 35.8 gas per worker per min (goes upto 42gas per min per worker when put 2 workers per gas)
tdlr:
gas or minerals, it takes the same time to harvest itso a infestor costs 100minirals and 150gas and 2/8*100supply = 275coins
so a zealot costs 2/8*100supply+100minirals = 125coins
building a supply depot cost (21sec buildtime+6.66sec traveltime)/60sec*42minerals per min = 19.4minerals lost from mining ===>119.4minerals for a supply depot
https://liquipedia.net/starcraft2/MULE_(Legacy_of_the_Void)Their timed life allows 9/10 mining trips which totals 225/250 minerals respectively on any mineral patch.
so a Mule mine 237.5minirals avg from your mineral field
when do so, you destroy avg 12.5minirals from your mineral field, without mining it
a standard mineral field have 1800 minerals
and a standard Geyser have 2500 gas1800*8=14400
2500*2=5000
So if you have 6gass workers, you could have 17.28mineral workers, and make your resources mined out at the same time
So i looks like a mule is twice as cost effective as calling down supply depots,
but a mule makes it happen that your minerall field depleats twice as fast as you Geyser, making you get 66.6%profit from a expension compared to a protoss player, amplyfied bye low gas costs of terran units
when a ''Calldown: Extra Supplies'' creates minerals out of air, and overall not requires workers that occupy supply.
So basicly you spent 150minerals to create a orbital Command, to make profits from air.
remember the build time of orbital command not allowing you to build workers, making the profits decay in the short term
instead of taking that profit, you wana double it, at the cost of your expension-duration+effectivniss
instead of taking the long term profit, you wana undo the short-term-gold lost on scv creations
Protoss dudes, stop chroneshift your workers, your delaying your tech/expension with minutes when do so, and you not gain alot from it
1)you start 12 workers, so you only need 4 more, and gass-miners, so why chronoshit workers, if you not expended yet and not have gass yet?
2)get gateway/tech first, so you can add gass asap, makes you allow 3-6more workers to use in main
3)you start 12 workers, building a nexus faster instead of spending it on workers-chroneshifted, will result in the same profit at the 2min mark
4)tech is everything, get your fcking zealot out of here
terran: You delay orbital command, never use mule, and call-down-supplies on all supply depots
zerg: Get gas and some tech. The use of gas makes you get 66.6%more profit from every single hatchery and larve
protoss: You only chronoshift when have a 2nd nexus, and you mostly chronoshift your upgrades, and long duration productions in expensive facility
it may be a bit 4vs4 orientated, but the theorie works for 1vs1 aswell, even when it may require some modifications to the current meta.
like the 3-3marines(no stim) 166.6supply 6min mark push, pretty good aswell in 4vs4, without alot of gas
