I think honing a razor is a balancing act between having the edge so sharp it becomes too fragile and crumbles and microchips too easily. However I wouldn't call that too sharp I would just say the edge was ruined. I think a razor should be as sharp as possible while still giving good service with multiple shaves. I find when I get an uncomfortable shave thats the first sign a razor needs to go back to the hone. .25 diamond is a special case because of the way it cuts with those big xtls but even then the harsh shave usually lasts for 1 or maybe 2 shaves. Its much easier to overdo it with diamond because it cuts so fast and aggressively.

I'm of the school that a razor need to be as sharp as possible. If not then you start letting yourself do some of the work as opposed to the razor doing it and thats a recipe for cuts and nicks as you begin to apply pressure (ow it hurts to even write that).
