Mineral Boosting Patch 1.1

Basically, when your worker finishes gathering minerals, they stand for half a second before turning around to bring it back to your base. sockfolder discovered that if you press the Return Cargo button on the worker, it will immediately turn around, thus giving you minerals faster. So to make this trick work well, you need to queue up the commands for each worker.

Select a worker that is holding minerals and follow below:

Hold Shift
Press C (Return Cargo)
Right click the mineral patch it was gathering from
Repeat steps 2 and 3 quickly
Be sure the last command queued up is the right click
Repeat the whole process for the other workers
According to sockfolder, after 5 minutes of normal mining, a worker would gather 495 minerals. A worker with boosted mining, would gather 530 minerals, which is 7% more! Check out the below video
