let me see if i get this right, conceptually.

my pot equity is determined by how many players are in the hand...currently. meaning, if there are 4 others in the hand, my equity share is 20% or one part of five total players?

theoretically, that SHOULD change as players drop off on later streets? meaning, someone bets, someone folds...now my equity share changed to 25%?

raising for value should be done when your pot+implied odds are greater than your equity share? meaning, i have a pair and flush draw to the nuts, the hand is 5-way, someone bets, another calls, i should raise for equity?

strictly by the book, taking nothing else into account...like reads on player, holdings, folding off the would be callers, etc., i will hit my draw and profit more often than i will miss and cost myself...for a net gain?
