About 85% of all robotic arms now have ROS 2 drivers

How are we counting robotic arms here? For example, KUKA sells over 130 different arm models, but you only have their cobots (iiwa and iisy models) listed here. Another example is that Kinova has ROS 2 drivers for their Gen3 arm but not their Link6 arm.

Based on the chart, would a more accurate statement be that “82% of arm manufactures tracked have ROS 2 for some of their arms”?
