I actually prefer schematics with the 'hop'. It makes it very obvious that there is no connection. Otherwise, it's possible that there should be a dot but they missed it.
I recently had that situation with a professionally drawn schematic of a commercial device from the 1960s. In that case, they missed the dot, but it took a while to realize that. If the drawing had used hops it would be obvious that two lines that crossed without a hop were probably connected. Actually, the mistake would likely have been caught before the drawing was issued.
Does anyone know why they got rid of hops? Was it just to speed up the drawing process rather than make it better?
