So it would seem. Perhaps I was being a bit optimistic for out-of-the-box performance: the brochure listed the holdover specs but said nothing about how long one needed to let it run before it was able to meet those specs. The user guide hinted at it when it said that a 24 hour training period was the minimum for good results (which I assumed to mean "will meet the published specs") but earlier tests after 24 hours of being locked to GPS didn't meet the spec either. Obviously it needs more time to stabilize and train. Hopefully my daughter doesn't eat it in the interim. > Let it run for a week.
