Well, in every videos we heard about range avantage on certain board and it's an important factor to decide how we want play our range.The obvious point is having a range advantage "allow" us to be more aggressive and vice versa checking more when not.

But what we really looking for ?
- simply equity R vs R ? and what is a big range advantage in equity (5%, 10%, ...)
- nuts combos (that we have and vilain doesn't) ...

Had run quickly some numbers and sometime we have an equity advantage but vilain has more nuts combos.

exemple 1 (just to illustrate, far from accurate)

hero open in sb 50%
vilain flat in bb (60% ! x%3bet)
on T66r >>> sb 53% equity but about only 5% trips+ and vilain (bb) has about 10% trips+

exemple 2 (opposite scenario)

hero 3bet in bb vs vilain otb
3bet 12% (99+, AQ+, KQ+ and "bluff")
vilain call/def 16% (66-TT, broadways, good suited ...) (4bet all AA and JJ)
on AJT hero 45% vilain 55% but hero have 17% set+ (vilain only 10%)

So what are the important points and how to use that.
I mean for exemple in cb spot on some flop we want to make a small cb (0.33-0.5% pot) with a high frequency and in other spots using big cb at lower frequency. I probably do an ok job at recognize those spots (mostly by experience) but I would like to have better understanding of why. Because it's the only way to use it smart in other spots (or other games). I think we can explain a lot by studying equity graph but not sure how to do it.
