In reply to Paul Udstrand.

This is my last attempt.

This is incorrect:

"they wouldn’t be if your density delivered more efficiency than my reduced density in SLP"

It simply does not follow. The only way you can make that assertion based on the data you're using is if you assume that SLP and Minneapolis are otherwise comparable. They aren't, for all the reasons that have been mentioned.

Thus the data your using do not support the assertion your making.

As for water, Jaromir pointed out to you already that Minneapolis sells water to other municipalities. That's not because it has more residents.
