Game in the Brain

There is a concept of Touch Time in Lean Six Sigma time and Motion Studies (Aka processing time). Its brilliant and simple way of measuring waste. Its basically the actual time the worker is touching the product in a value adding way. Its such a revelation to me because it applies to Ideas and Information and not just materials.

Am I adding value to the idea?
Is my GM or the Player adding value to the Idea?
How long am I processing this idea? How much value am I adding to it?

Now its relevance to RPG is how much “touch time” do we have in Mechanics and Ideas? This is exemplified by the GM who creates a lot of Fluff and how much of that fluff is “touched” by the Player’s minds. How much of that fluff is handled by the Players.
Like in Touch Time studies its as simple as who has Known the Idea and remembered that idea, and who it matters more.
