SHEEEYA! Challenge gleefully accepted! As the ever-brilliant Alice Keeler would say, "The answer is always a spreadsheet!" (**I would beg to differ that the answer is typically "more cheese," but in this case, her answer works better.)
For this challenge, I created a very simple chart in Google Sheets, with rows for the dates of the challenge, and columns for each of the classes. You could do a similar Sheet with columns for each student, but this time, they are doing a class challenge and wanted to pit "teacher vs teacher." Once the data cells were built, I simply deleted the extra rows and columns (for a more tidy appearance - they're easy to add back in), and changed the fonts and colors (to make it pretty).
If you've never created a chart from a Sheet before, never fear - it's easy to do, and you can always delete it if you don't like what you see.
Once the chart is inserted, it's time to start adding data. The graph will automatically update as data is inputted, so there is no need to redo the chart as you and your teaching partner start logging your minutes.
Here is the real live chart, so that you can see the progress as this competition progresses:
