This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Maybe my eyes are gliding over it, but does anyone know what the actual difference is? They've got relative "+80" to "-80", but no indication of what those units are. Would I be 1 kg lighter between the highest and lowest spot or .0001 grams lighter?
Based on Wikipedia I think the unit is milligals, where a gal is 1 centimeter per second squared.
That is a bit of an odd unit where g is ~980,000 milligals.
So these changes are extremely small.
So then the total variation is all within about 0.02% of gravities normal value
The article says it's "slightly different", I imagine of a few grams, cuz a difference of 1kg between zones would be exaggerated.
