Nice map makes for good practice. for any who use this, if you take off south until you are about half way to the altitude you want to practice and make a slow turn north by the time you are over the base you should be at about 25k or higher,
This is start alt is 12k head south till about 18k or 19k then slow turn north when over you launch base alt is about 25k or higher. makes a short run and now you can calibrate it.
Thanks for the MAP
