Marathon pace variation curve

I like the pace charts posted on the Twin Cities Marathon website. They show the mile-by-mile pace, starting and ending slow with a faster mid section. I created my own version of this in a spreadsheet based on my target 3:27:05 time. I will probably add an elapsed time column and print a wristband to use at Fargo. Here is my chart based on a 7:55 average pace:
