Change a few words, and PRESTO:idea:
Ranging bet sizes and the Kelly criterion
Between 70% and 90% of the player edge when counting cards comes from placing larger bets when the count is favorable to the player. (The rest of the edge comes from changes to basic strategy based on the count.) [12] A mathematical principle called the Kelly criterion indicates that bet increases should be proportional to the player advantage. In practice, this means that the higher the count, the more a player should bet on each hand in order to take advantage of the player edge. Taken to its ultimate conclusion, the Kelly criterion would demand that a player not bet anything at all when the deck doesn't offer a positive expectation. "Wonging," as shown above, takes advantage of that.
