Too maximize it you basically have to keep your eyes glued to the heat gauge, ammo, and hot bar.

I feel like the better I get and the higher numbers I get is when I can start counting Heat and Ammo in my head. Sometimes I won't look at my heat for over 15 seconds-ish and it certainly helps with avoiding mixups. Still have to keep one eye on your bar for your 1-2-3 but I've been doing that for 2 years now.
