Doubling or Halving as a Game Balancing Technique
A game balancing trick that Schell attributes to design Brian Reynolds (who in term attributes to Sid Meier): when tuning values to balance a game, don't start out by adjusting them by a small amount, but either double or halve them in the direction you think they need to go. It gives you a much clearly picture of the value you are changing and prevents you getting stuck "in the weeds" wondering if the value had an effect.
Schell (2015) (pg. 233)
Since it a technique for problem solving game balance issues, it's related to Game Design is Problem Solving.
