If I, and other readers understood right, Janus58's position, and the Frederick graph show, that in a constant density globe/spheroid, a reduction of radius at the poles, will lead to a reduction in surface gravity there. so, If there is the opposite, an increase in measured gravity, the body must not have constant density, and not surprisingly, the Earth does. Do not ~ constant density spherical bodies form because lower areas have less gravity? would increased gravity with depth there not create ever deepening holes? once triggered, runaway oblateness without any spin?
