When biking to work, my routes have have stop signs, stop lights, and other interruptions every few blocks or so.
My understanding is that if I reach my power at target heart rate soon after stopping so that I still save glycogen, my commutes would be faster. I'm commuting five days a week. How effective is it really in practice? How much would I expect my average speed to increase?
Update with examples.
After stopping at stop signs, I plan to accelerate by keeping my power around 150W depending on my fitness.
After stopping at traffic lights, I plan to gradually raise my power to 150W because my heart rate would drop.
In both cases, my heart rate shouldn't exceed 180-age. With power, I know that I'm not overshooting it.
