Gotcha. I thought it was just my crappy Earthmate that was slow in reporting. :-)
I imagine that in the infancy of consumer GPS, a 1Hz sampling rate seemed perfectly adequate, especially when the application was for a handheld device that wasn't capable of moving at 60+mph. Especially pre-2000, when the signal was still degraded anyway.
Thanks for the info, and good luck with your test. I'm currently studying for USMLE (that'd be medical boards/licensing exams), so I feel your pain, even if I don't envy your position.
