The max speed is the speed when the cims are at 5300rpm in an ideal world. In reality, some speed is lost to external influences (generally, I use 80% ideal for my calcs, but it varies). The mentor who calculated 19fps may have used a smaller loss constant.
3000rpm seems pretty low even for a relatively low-tolerance robot, but I could be wrong.
