No worries. Words come across oddly in text sometimes.
In regards to any sort of policy on how to give dates, its mostly like, if you run across something, feel free to drop a post here with it, and I'll try to update it. Having a news article or something to support the release date/regions helps lots.
For Gundam Breaker, I checked around when you mentioned it, and found
an article back that date, so no worries, that date looks ok.
The articles on the official Playstation blog has alot of upcoming notices, which can be good, if one is already checking those out. Checking both the NA and EU helps clarify if a title is in one and or both regions.
