I’m trying to wrap my head around how for the same ride with slightly different average powers (234 vs 235) the time for the 235 W is 12 seconds slower. Same weight, same bike, no draft or power ups. This is for the Alpe du zwift so lots of changes in the gradients. If you attacked the climbs vs flats but averaged the same power would the times be different? I’m sure it’s true but I just can’t wrap my head around it. Could someone explain it?
