Getting a jet swapped between sessions takes more time than it looks when there is a driver waiting to go out. I get that you drop jet size if the air thins out but I'm wondering how much of a change actually makes it worth the hassle on a Comer c50 or c51. Does anyone just set a baseline and only touch it if the day is really different or is there a practical check that doesn't eat the whole morning?
