Tools for managing and analyzing performance data

Hi all,

When organizing logs or tracking performance, sometimes dive students, trainees, or instructors need simple tools to compute weighted averages beyond just dive times for example when combining training scores or academic records with dive performance reports.

As a reference for general weighted averages across different metrics, can help compute weighted averages accurately.

Just curious how others handle data analysis or complex scoring beyond dive logs? Any workflows or external tools you’d recommend?

Thanks!
