The difference is the gearing advantage of the 5-spd (closer ratios and higher torque multiplier) put the engine in the peak torque-peak power band for more of the acceleration run. This more than offsets the delays of shifting. That said, you're correct that shifts take time to complete and more shifts = more time so that takes away some of the gains from the more optimal gearing.

More of a factor on a road course where gear selection is more critical to acceleration off a corner.
