spot meter at the brightest area where you want to keep detail, then add 1 stop

If your goal is color, overexposure happens when the first color (usually green) passes the limit of the raw file. If you are converting from color to B&W you might not care. Looking at the RawDigger histograms will make this distinction clear.
The fact remains that, if your camera places exposure zone 5 between 1000 and 2000 for a 14-bit raw file, there are only about 2 stops above that for the JPEG or 3 stops for the raw file. You really should not cut it that close. Backing off a half stop would be wise.
So it's down to the DR of the scene. How far above middle gray (in the middle of exposure zone 5) is the brightest highlight where you want to retain detail? If the DR is narrow, you can expose further to the right. If it is wide, you will probably have to make exposure zone 5 darker.
