The messages are clear. Get ready to race!!!! Not with one exclamation point, but four.
Coaches and swimmers have been doing test sets for decades. The memories and results and style of operations can be simple, clear, direct and functional. Results can be transcribed, later, to a spreadsheet or database. The results can be preserved in a simple cell phone photo too, of course, as posted here.

Document and remember
One missing element -- what stroke the swimmers within the set. Some might have been doing free, while others were doing back, breast, fly or even 100 IMs. That data is absent. The coach and swimmers would remember that within the season.
Chalkboards work too. Messy. Still gives a focus and higher level of seriousness to the activity if it gets written down and recorded. Different test set, different team, and different way to remove the kids' names, by not spelling them all out at the outset.
