Micro has a general advantage of growing at a rate of N^2. That is, 10 Zealots, with perfect micro, can perform roughly as well as 100 Zealots with the worst micro possible.
Ex: 100 Zealots come in one-at-a-time vs the 10-zealots in an inverted-V shape. The 10-zealots will defeat roughly 100.
The bigger and more complicated the board gets, the more and more micro becomes favored.
Only at human speeds.
Once you break the 10,000 APM barrier however, Zerglings start to dodge-tanks and other shenanigans begin to happen.
