Bill can you explain how to use this chart to make decisions in the field regarding ISO settings?

This chart simply gives you some idea of there the "ISO Invariant" areas are.
Personally I don't ever make ISO setting chooices based on this type of information.

Also why is there a dip in the chart between 200 and 400? Very interesting stuff thanks!

It's a mystery. One theory would be that noise reduction is a little stronger at the ISO setting.
