surprising it's just I just like it because of the nature of how we formulated it so dynamic pricing is obviously helpful all right and and already there's a hint in this second-order effect that I mentioned and really like why do we use it well one reason we use it is because we don't want to have to sit and futz around with what we think the system parameters are actually going to be even when it's predictable uncertainty all right so one thing that's nice about dynamic pricing is it sort of naturally adjusts itself
