Recently ive been questioning myself, if im developing a bad habit with the current control groups im using.

I use:
1 - Total Army
2 - Support units
3 - Orbital Commands
4 - Barracks
5 - Factories
6 - Starports
7 - Engineering bays

I want to improve in SC2 and im wondering if my current control group hotkey setup is going to hinder my progress. (I feel that i need 3 total hotkeys to manage my army efficiently).

Q: Should i take the time to learn and push my current 3-7 keys to 4-8 (1-2-3 for army)?

I mean im trying it atm on my NA account, have played about 10 games, and i cant cycle through my buildings as fast as i use to. (eg 3s 4adad 5s 6d 7ea) would be a complete cycle (not necessarily always doing that). With the new setup (5 barracks, 6 factories, 7 starports) i find that doing 6s 7d with my left hand is really hard and it slows me down a lot. Is that why i see koreans macro with 2 hands on the keyboard sometimes? Is it worth it in the long run to learn my new setup so i can micro more efficiently when i get better?
