Unknown Row and Column entries

Good day,
So, I am trying to develop an App that log times (seconds) according to an Athlete (Bib No)
I have tried to write to a normal txt file, but maybe I do it wrong. Is it better to use TinyDB?
And also, If I know the amount of entries, it would been easy to create the table, but every race is different.
Each Row must represent a Bib number, starting at 1, while the times is being added to each Bib Number. Also, it must handle multiple time entries per athlete, for example I have 10 athletes , running around a track, for an hour. This timer will log each lap time according to their bib number.
What is the best way to do it, and any examples perhaps? I am getting confused with Lists and index vs Tags. For example, what do I use to get the row I want to add to?

bibs1

Any help will be appreciated. I am a noob here :frowning:

Thanks,
Jakes
