Richie: your point about throwing the results away is valid when multiple calls to LinearFibonacci are made. However, it seems that Peter considers only the performance of single call to LinearFib; by modifying LinearFib according to your suggestion the running time will still be quadratic.

However your point is noted when the application requires multiple Fibonacci numbers - dropping previously computed results is a bit foolish then.
