And I'm at plump.magpie.tightest (sorry, no calculated height available, 
not even in annoying feet - but I'd guess somewhere around 2 or 3 metres).

I mean, is say latitude just one integer showing seconds, or is it deg, min, sec - and are fractional seconds returned (so, floating point)? I shall find out for myself eventually but it would help a little to know now. AFAIKS there’s nothing in the LC documentation about it.
