Having low board coverage against high range is valid strategical tool in poker and widely used for example when choosing
bluff 3bet hands or raising range on the flop.
Having low coverage is not dominant tool though, meaning it’s only used as a backup giving you some extra EQ. This is not something you desire to drive your game to because small pair is worse than big pair, and low straight is worse than high straight etc. In the long run this strategy is losing one if it’s the only idea behind the play.
Not that it’s matter in this topic, but maybe someone with interest of learning the game is reading this too.
Overall there will be low flops and high flops in a cyclical fashion usually not exceeding what I call the rule of ''3" in a row
You use lot of energy to make theories but are too lazy to actually test your theories. I don’t like that at all. If you would be honestly interested about math behind poker you would a) read a book (any book really), but Bill Chen's "The Mathematics of Poker is the king warning though that book takes about a year to understand and learn b) would learn to use any math program that can do random values I suggest for example
