Tom,
Keep in mind the GPS12 (and I still have mine) is
about 12-13 years old, and was a handheld navigational
receiver. No mapping support, no timing support, no WAAS,
no DGPS, proprietary Garmin serial + power connector on the
back. It's a very basic receiver.
It was never, ever intended to be used for timing,
and attempting to use it for such results in amusement.
I agree the behavior is very odd indeed, so yes, it's an
oversight on their part, but I'm not surprised.
I didn't even bother to observe mine.
