You can use my site to track your progress vis-a-vis the 100 segment qualification. Choose 100,000 as your end-of-year goal. Then, in the box labeled "Year-to-date miles", enter your year-to-date segments times 1000. So if you've flown seven segments year-to-date, enter 7000.
In the resulting analysis, replace "miles" with segments, and divide all numbers by 1000. So if the program reports "you are 2,254 miles ahead of your goal", that means "you are 2.25 segments ahead of your goal."
That should address your needs in the short run. If demand warrants, I can revise the system to include a more intuitive segment analysis.
