Agreed,
Regarding this chrono thing, they are nice to have but definitely a want vs a need kinda like a consentricity gauge, use it once or twice then it grows mold.

Can be used as much or as little as needed depending on what you're doing. (1) I seem to be constantly working up new loads and finding new powders and projectiles. (2) It is helpful to find comparable combinations AND to verify lot to lot consistency of powders. For those that need one, it's invaluable.
I have no doubt that mine will likely see long periods of disuse, but so far, a month or two has been the interval.
