Mike et al., Thanks very much for confirming what I already thought. My
first reaction when I read the reviewer's comment was if you do it all
in one step, there's no way to check intermediate results for errors. 

I guess all people (including our reviewer) have their own pet methods.
That's fine, but they don't need to impose them on others. Your (pl)
comments will be very useful when we submit our revised proposal.
