Thank you! I added some in-line comments. Please have a look.

Should we add the plots to the evaluation page?

Should we add the plots to the evaluation page?

The performance data may still change, and I’m concerned that once binary image files are added to Git, they’ll be difficult to replace later. Perhaps a good approach would be to use some scripts embedded in the documentation to generate the plots online.

Let me also revise the plots in PR #29.
