Although it seems to me that you may be missing the point about what breakpoints are for.

The first thing you ask yourself when you reach a position that the layout breaks "is there something I can do at this position that means I don't have to add a breakpoint? If the answer is yes a little bit of adjusting will work then do the adjustment, if the answer is no, nothing I can do, then go ahead and add a breakpoint.

The two breakpoint amounts you mention are so close together, I can't see what benefit there would be for a visitor.

I was talking about the CC menus in your link.
By moving the breakpoint you'll keep the style settings. If you create a NEW breakpoint at your desired pixel point and then delete the existing breakpoint, you'll have to add the styles from scratch.

Who would have thought it was so simple!! Thank you everything worked out.
