A more useful metric would be something like "it goes covers 20 feet in 2 seconds from a stop". That's something that's actually somewhat easily measurable and useful.
The value of everyone using free speed to talk about gearing isn't in being able to literally use the number as is to know the robot's top speed. The problem with using adjusted speed is that everyone uses different constants and parameters to define what their adjusted free speed is. Geared free speed puts everyone on the same page, and the reader can apply their own constants to adjust that free speed if they so choose. It's just a known benchmark that's easiest for everyone to agree on in order to compare robots to each other.
