How this works
From where you stand. Distance and pull are measured from your spot on the surface, not from Earth's centre. When the Moon is high you are up to ~6,400 km closer to it than when it is under your feet. That is the daily wiggle in the chart, riding on the monthly swing between perigee and apogee.
The scale. 0 % and 100 % are the 5th and 95th percentile of the past 365 days at your location, sampled every 30 minutes, so about one reading in ten lands outside: below 0 % or above 100 %. The thin ticks are the year's minimum and maximum.
Your weight. You and the Earth fall toward the Moon together, so you do not feel its pull directly. What changes your weight is the difference between its pull on you and on Earth's centre, which is the tide. It makes you lighter when the Moon is overhead or underfoot, and heavier when it is on the horizon. Not included: the solid Earth's own tidal flexing (about 16 % more) and the Sun's tide (about half the Moon's).
Accuracy. Positions follow Meeus, Astronomical Algorithms (1998), ch. 47, good to a few km and ~10″. They are checked against published perigees and the astronomy-engine library. Everything runs in your browser. Times are in your device's time zone ().
