I haven't seen anything on the internet to help me completely comprehend the idea balance and how it applies in game practice - 

FWIW I dont have well thought out ranges in any spots except super roughly my flop cbetting range on different boards (just because that spot probably comes up the most).  I play 100plo on stars full time. 

At lower stakes, knowing the game,  playing your A game while looking to exploit fish is more or less sufficient enough to win.  

So against other regs - if im at least aware enough to not play my hands too standardly, and to not bluff in the same spots over and over, or to have a rough flop cbetting range/checking range .....is that sufficient enough to not worry about it ? Do I need to develop/widen my range in spots even at 100plo ?

Or are there players who are seriously winning because of balance/they actually are so in tune with other players imbalances ?

If so, how do I become aware of other players who are balanced ? 

How many .50 - 1 and 1-2 PLO players on stars are aware of balance in the games ?  Anyone beating other regs based on specific balanced or imbalanced play ?

If you consider yourself a relatively balanced player, 

How long does it take you to figure out if a player is balanced in liveplay ?

How hard/easy is it to exploit an unbalanced player ? 

How important is the math ?
