I don't change the multiplier on the basis of the exact number of available drivers that are in the system so but you should be thinking when I say static is that idiosyncratic stochastic fluctuations are not being captured by the by the dynamic pricing policy so so in math this means that P of a is a constant for all a that no matter what the level of the queue is I'm setting the same multiplier so there's a theorem here that you know don't worry about reading the technical sort of expressions carefully but here's
