Richard not to hijack the thread and definitely not to throw stones, but I was wondering what DCR calculator you are using and whether it takes altitude into consideration. One of the things I noticed when running the numbers on the 283 when I was building it was that altitude made a significant difference in the DCR.

In my case I needed to take into consideration not only where I live (4500 ft) but also where I vacation at (200 ft).
