Hmm, something wrong with my calculations here?
My mistake. I calculated the factor, but forgot to multiply by the 10 minutes. I did it on a calculator, so I guess it's a good example of why one should use Mathcad, not a pocket calculator! With the correct calculation I get 5.8 days. Ouch! Time to buy either a much faster computer, or a UPS!
Not in the wheelchair, too, but maybe close ;-)
If the time comes, keep on rollin'. As long as the mind works, life has many rewards. Anyone that disagrees can go argue the point with Stephen Hawking
