When I ride my bike to work sometimes I pedal hard between lights and sometimes I cruise in LSD mode (long slow distance)
Sometimes I'm in the mood to go fast and go all out even though I have to stop at every light . Sometimes I time the lights and just cruise along and never have to stop. Either way gets me to work about the same time.
When I cruise people will pass me and then I float by them at the next light then they pass me again, etc, etc, etc ...
I know there is some time of life lesson here I just haven't figured it out yet Grasshopper.
