multiplier that I'm going to use the blue curve is the throughput that I obtain if I just set that multiplier regardless of the number of available drivers same basically as the curves that were showing you in the previous graph which is pure static pricing okay the purple curve is what I get with a very particular dynamic pricing policy the dynamic pricing policy is one where one of the two multipliers is set at green at this at this point right here and the other multiplier is the one that's bearing on the x-axis okay now
