In an unscientific comparison, I have just put my laptop down in the living room, walked (quickly, I can’t run in flip flops) through the hall, kitchen, utility room and into the garage, navigating 2 doors and a dog wondering WTF is going on, got my bike out of the work stand and mounted it and it took about 20s.
If their bike swap took 50% longer than that I reckon there’s some [whatever the opposite of marginal is] gains to be had.
I can also confirm flip flops aren’t good for moving at speed, and will not be recommending them to the athletics team.
