Enough with that chart. It's garbage. It always was and always will be. The way to read Discworld for the first time is in published order

Sure, the books don't always have the same main characters. But they do have a lot of the same locations and same background characters. They are as much a part of Discworld as the main characters. So by reading out of order you spoil the locations and background characters. That makes the series not as enjoyable. So please stop trying to spoil Discworld for others.

The problem with that reading order you've recommended is that reading out of order because you don't care for the Rincewind books, you then have people reading them basically all in one go instead of spreading them out.
