If anyone is interested, visit the project page https://pypi.python.org/pypi/rowingdata and if you need help, send me a PM. Use with caution and at your own risk.In the past few days, I have been playing with some Python code that gets data from a TCX file (captured with CrewNerd, for example) and create nice plots.
I've also successfully used it to create plots from RowPro CSV files, as well as Painsled (both iOS and Desktop) CSV files.
To make my life easier, I have created the functionality to upload my rows to the C2 logbook. For the erg data, I would strongly recommend using the C2 Utility. My code currently adds the "waiting" time, when you have dialed in the row but haven't started rowing yet, so paces are slow ... Still, for getting OTW data on the logbook, it is much easier than manually typing the values into the form.

Finally, I wanted to thank Free Spirit Greg Smith for developing the plot algos in the first place. All I did was wrap it in a package, add a bit of functionality on the side, and create a Python package for everybody to install. I hope I didn't breach his software license ...
