The critique likely stems from the idea that combining performance factor, torque, and DOFs into a single comparison oversimplifies complex engineering concepts. Torque and DOFs are distinct mechanical properties, and "performance factor" is a vague term without a clear definition. Such a chart might misleadingly suggest direct correlations where none exist, leading to confusion or misinterpretation.

In essence, the commenter is expressing frustration over what they see as a technically flawed and potentially misleading representation of robotic performance metrics.
