Are GURPS Tech Books released in wrong order / badly planned?

Everything has a little arrow sprouting from it, pointing to its ballistic position in +n time units. n can be adjustable with a thumbwheel perhaps, and you can dress up the arrows by graduating them in color, so you can make sure that you don't intercept some object while touching your arrow tip to the subject's. This works for projectile weapons as well, per its use in John Varley's story, "Equinoctial".
