Site anonymizing for Skyderby Flysignt track uploads
If you were worried about uploading your Yosemite jumps on Skyderby:
Open your .CVS track from Flysight in Excel. Type any random number (like 12.34) in a free cell, Copy that cell (as in cut'n'paste, Ctrl-C), then select your Longitude column cells (not entire column, only non-empty cells!), click on Home, Paste Special, Add. Finally, delete your random number, and save your file.
You now have the same track shifted thousands of miles away by the random coordinates you've typed in, ready to upload on Skyderby or share elsewhere.

A nice, easy solution. Thanks for sharing. Do you find, nowadays, that there is widespread concern about secrecy of exit points?
One shortcoming of this method is that your latitude obviously doesn't change, and that could be a big clue if it correlates with a well-known, illegal landmark. Especially if your flight path fits a recognizable pattern.
If anyone is concerned about this latitude being preserved, I made a spreadsheet several years ago that addresses it. You can put in any new starting latitude, longitude, and altitude, and the spreadsheet automatically calculates new waypoints at accurate distances and bearings. One thing I didn't bother to add was a "rotate" feature but that would be pretty simple if anyone were to ask for it.
