This is an eminently reasonable suggestion, and I have endeavored to take it.  I find I need more time to formulate the results of my analysis, but they do not lead me to the same conclusion that Herbert has reached, that we should start over from scratch.  However, we can, perhaps, consider each of the changes in our current draft, as Herbert prodded us to do, and evaluate them against this group's mandate and objectives.  We might now draw different conclusions about some of them.

I decline to work on this over the weekend, and Monday is a U.S. holiday, so it will be at least Tuesday before a I respond more fully.
