Guesstimating firmware performance

Abstraction conses af a price. In too many cases we´re losing the “feel” of the problem. The flip side of a “feel” for a problem is an ability to combine that feeling with basic arithmetic skills to very quickly create a first approximation to a solution, something often called “guesstimating.” This word combines guess-based on our engineering feel for a problem-and estimate-a partial analytical solution
