Added some clarity and another change counter/edit example
Giving unnamed segments a street name in that operation might get you more points in some cases. Allowing/forbidding a turn counts as a change in the node of the turn, so all changes in the same node will be granted only once.
Editing the same object multiple times in a single 24 hour period will only result in one
point for that object in that period. The changes will be saved and made to the map, but not your total score. Also, when saving a large number of changes at once, the system will not credit you with more than 150 point per save. If you have more than 150 changes stored up before you save, they will attempt to save and update the map, but you only get up to 150 edit points.
===What's the Difference Between a Change and an Edit?===
In the first example, those 10 segments changed all at once will get you credit for 10 edits. In the second example, those 10 changes will get you credit for 1 edit. In the first, you changed 10 different objects. In the second, you changed only a single object.
For those more interested in the details behind the calculations you can review [http://www.waze.com/forum/viewtopic.php?f=14&t=10760&start=190 this forum thread]. Additional changes made to the point system are noted in [http://www.waze.com/forum/viewtopic.php?f=276&t=28271&p=435857#p435905 this later forum thread].
