What is the conversion factor for 29.97? For most, this would be easy, for me, my head starts to spin.

it's telling you the standard altimeter. if the pressure rises .08" of mercury, up to 30.00...it results in a decrease in altitude of 73 feet. if the pressure goes from 29.92 up to 29.97, it's going up .05" of mercury. based on our rule earlier...
1000/1" = x/.05" (1000 feet per 1 inch of mercury) = (x feet per .05" of mercury) should be 50'
