Manic Monday: Boil

I wonder... what is the time difference of boiling something at sea level (needs to reach 212.15 °F) to boiling something at my elevation (needs to reach 202.89 °F). I know it would be a shorter time, but I hardly think that leaves me at an advantage. Reading up on a water-bath canner I notice that for my elevation I have to increase the processing time an extra ten minutes. That hardly seems compensatory. I don't think it takes ten minutes longer to go an extra ten degrees in temperature....

I guess life isn't fair sometimes, is it?
