Last time for this one--if you find that stretching helps you, I'm not going to tell you it doesn't and you should keep doing it if it works for you. Just stop telling me or others that we should do it because it works for you. Muscle elasticity is a genetically determined trait, and it varies like crazy. You don't have any special knowledge that lets you know what should or shouldn't work well for someone else.
BTW, I just figured out what my stretching activity is-it's called standing on the pedals.
