I checked the 5 stations in 10 minutes this morning. It is now behaving that way. It appears each station update has it's own 10 minute limit. For example:
Station 1 update 09:00
Station 2 update 09:00
Station 3 update 09:06
Station 4 update 09:06
Station 5 update 09:09
At 09:10, you will be able to update two more stations, 09:16, two more, and 09:19, one more, etc. If I'm wrong, sorry, but I didn't start writing down actual times when I started my commute this morning. Just appears that is how the updates work now.
My back road commute to work each day is 28 miles and I pass 28 gas stations. Now I can only update/verify about 10 of them.
If Waze wants to prevent 'point farming', make the points apply ONLY when you update a new price and not when a price is confirmated. That would also prevent the 'sending update' stuck state from displaying. And I agree with AlanOfTheBerg in that Waze should have updated us in this thread or at least a new informational forum post.
