-Now, take your calculator and fill the below table with the results from your experiments:
-
-\begin{tabular}{| l | l | r |}
- \hline
- Step & Duration & Description \\
- \hline
- \hline
- U-Boot SPL & & Between \code{U-Boot SPL 2022.04} and \code{U-Boot 2022.04} \\
- \hline
- U-Boot & & Between \code{U-Boot 2022.04} and \code{Starting kernel} \\

- Kernel & & Between \code{Starting kernel} and \code{Run /sbin/init} \\

- \hline
- Application & & Between \code{Starting ffmpeg} and \code{First frame decoded} \\

-\end{tabular}
+Now, run the test 3 times and using LibreOffice Calc, fill the \code{Run 1},
+\code{Run 2} and \code{Run 3} columns in the table in the
+\code{~/boot-time-labs/results/initial.ods} spreadsheet. The averages and standard
+deviations of the measurements will be computed automatically.

+Here's the kind of results you should get after filling the table:
