worth noting that the amount of watts you make from 10-15 seconds of an effort (or from 15 to 20 seconds into the effort) is a lot lower than your peak power, but determines your max speed a whole lot more.
which is to say if i had to choose between a 2000w max with a 1000w 15-second average, and a 1400w max but a 1250w 15-second average - guess which i'd choose? guess which would give me a higher top speed?
you have headroom to increase your max wattage, but if you wanna go faster, focus on *drawing out* your max wattage - doing it for longer.
