Reader Gordon H. Ward kindly writes: “Not being a computer geek I may have misread the fourth column in today’s message. I believe that 9.3 Mb is 94% more than 4.8 Mb not 51%. It was probably a misprint.”
Mr. Ward is partially right: His math is flawless, but it wasn’t a misprint. I miscalculated, using the wrong formula to figure out the percentage. Mea culpa!
