What?
In 2007, we were one of the most consistent teams in the country scoring the tubes on the rack-n-roll rack. We were consistent to about 1/4 inch true position through the use of a gyro, two encoders, and knowing the center of turning of the robot. We were skid steer.
In 2008, we consistently did 4 lines unless we were blocked by another bot, and we knew exactly where the robot was going to turn and end up. Using skid steer, a gyro, and two encoders.
In 2009, we had the robot set up to accept an angle and a distance from two dials on the board so we could put it anywhere we needed it (barring collisions of course). We didn't account for side skid just for simplicity's sake. We used a gyro and two encoders.
Skid steer is extremely easy to navigate with by doing constant angle / distance calulcations at a decent rate and averaging them between the sides. In fact, functionally, the math is no different that the trig you do with the swerve.
On what do you base the idea that not many people with skids have done much with navigation?
