Gravity would also be measured as a lesser force because we're subjected to the effect of gravity on a galactic, and likely universal level as well as the systemic level. We base our measuring on a terrestrial and systemic level, but we don't know the level of gravitational influence on a galactic level much less a universal level.
So it's like measuring the speed of a watercraft steaming down a river that has a very heavy downstream current. How fast are we really going?
The analogy is simply to illustrate that we're completely affected by gravity, so measurements will be certainly less dramatic than what the glory of gravity implies. inhuso (in my humble unscientific opinion.)
