Although it is at times somewhat whimsical

, this trends deals well with a systemic issue: wear is analog (in an infinite number of steps), grading is digital (in a limited number of steps). How many steps you need is a personal matter.
Until quite recently, church bells rang every 15 minutes and that was enough for most people. Wind-up watches gave time in minutes, until a hand for seconds was added, but they weren't very precise. Computer clocks align with atomic clocks. They are very precise, but who needs it? So it is with grading. Grading Greek and Roman coins is a church-bell system with 3 to 5 grades. Grading later coins is a wind-up clock system outside North America. North American grading is an atomic clock system, except that there's no atomic clock.
One of the many benefits of computers is that it is quick, easy and virtually free to make and send a picture. For me, that translates into two situations you might call "who cares" and "send me a picture, please/I'll send you a picture". For those who argue that pictures can be doctored: you mean grades are always honest? Bye bye grading.
