It is not so much the proper RPM but the difference in RPM between gears. If you up shift at 1800 and going in next gear you are at 1200, then you have a 600 RPM split between gears. So downshifting you would be around 1200 and would while floating gears or double clutching bring the RPM's up to 1800-1900. Many trucks have RPM range stckers on the visors my old Mack was 1050-1750, that's a 700 RPM range, I would down shift when I hit 1050-1150, at 1150 I would have to bring the RPM's up to about 1850 to get it to go into gear.
