i don't know.. after playing xxxxx games with zerg you get the 44.44 seconds between injects pretty much right

like, just because of my experience i inject my shit every 45 seconds .. it's just practice you know

inject larve = stop hatchery larve production, untill larve is used

so, 46%more miniral cost per larve spam if not use queen inject
the benefit from queen is lost, if have a x second inject delay
x = ...






asume you have a delay of 10seconds at normal game speed (5sec fast game)
hatchery larve cost increases, 54.44/44.44*87.5 = 107,2miniral cost per larve per min from hatchery instead of 87.5 couse inject larve have a 10sec delay

4larve per 54.44sec from queen for 175minirals = 39.7miniral cost per larve from queen

avaraged out that makes (39.7+107.2)/2=73.45 miniral cost per larve spam per 1 min, from 1hatchery and 1 queen
thats 19%more minirals needed if only create larve from hatchery
so +/- would mean if you have a inject-delay of 14sec as avarage over the full game (7sec fast game speed) you completly undo the cost benefits of inject-larve

thats in consideration that you also stop build units in this 14sec inject-delay
and that if you use hatchery only, you create 1 unit every 15sec, or 3units every 45sec, whitout delays stopping hatchery larve production

so if use a perfectly timed larve inject, you should inject and build 4 units all asap after you get the 4larve from previus injections, whitout stopping down hatchery-larve production

e/
There can be a maximum of 19 Larva on one Hatchery. Additional Larva produced at that Hatchery instantly die.

Im terrible but I just set all my injecting queens to one control group.

Shift+V spacebar click spacebar click spacebar click, its nice because if my APM is needed elsewhere i can inject all my hacths in half a second

I really just need to start doing this.

it's good to have it bound if you need to inject in a hurry, but overall it's way too sloppy to be your go-to inject tbh

as I stated before, this style IS faster than the 55/66/77 or the camera hotkey one, BUT for me it didn't work when I tried it for a week, BECAUSE in case you have 3 queens and 4 bases for example, this technique leaves your queens running around the map helplessly

so you'll end up looking for them like all the time over the map.. >.< no fun i can tell you
