The new software designed for scoring competitions that has just been released, called fs (http://fs.fai.org/) has just simplified an unnecessary policy about difference between the entry and exit start gates.

The software makes the logic assumption that the last crossing of the start cylinder is in fact your start time. If its an entry or an exit does not need to matter at all, and so the flight computers (Brauniger and Flytec 5030-6030) wouldn't need to make this distinction at all. The "Entry" or "Exit" discussion ends up when you take a look at the logic of the whole problem, and the way the FS software deals with it.

The theory plain and simple says that if the next turnpoint is outside the cylinder, then the last time you will cross the line would be going out of the cylinder. On the other hand, if the next turnpoint happens to be inside the start cylinder, then the last time for crossing the start cylinder would be the last time you enter the start cylinder. So this way is not important the way for crossing the line, but to cross the line just after your selected start gate time, and then fly to your next turnpoint.

I'm incapable of thinking of a scenario where the task committee would force an entry start gate where the next turnpoint is outside, or an exit start gate when the next turnpoint is inside.

If we start dealing with this nice and simple theory, and keep the software as it actually is, without introducing the exit/entry variable, everything will be simpler. Perhaps the next firmware for the Brauniger/Flytec won't have the "entry" or "exit" input field, as it's not necessary at all.
