You're correct susu.exp. It depends on the span of time under consideration. Many people confuse phyletic gradualism with what Dawkins has called 'constant speedism'. Even during cases of punctuation the evolution is still gradual, just compressed. As the OP has stated, the punctuations need to be put in the context of evolutionary time scales. It all just depends on what you're trying to model.
