From what I am thinking on my ranking on my 100% complete set..

LeeBone

Maybe I'm way off but, help me on this one...
I have a 100% complete registered set, and I am seeing higher ranked sets that are missing 1, 2, or more coins.
What I gather by my research is that if I were to delete my lowest graded coin from said set, I could jump up in the ranks because of my average grade%. Am I correct by thinking this way? If so, that really doesn't make sense to me. I have a complete set that ranks lower because of average grade% while their sets are incomplete and because of this rank higher in average grade%. If that is the case, shouldn't there be a way to rank sets by 100% completion instead of just grades while missing harder to add/find coins to ones set?

You are incorrect.

Each coin you add (include) in your set, regardless of grade, adds to your “Set Rating”. It is the Set Rating and not the GPA that determines ranking. Go to the “What if” tool and remove your lowest graded coin. You’ll see your GPA rise, but your Set Rating will drop. If someone currently ranked below you has a higher Set Rating than you after you hypothetically remove your lowest graded coin, you’ll then see that you’ll drop below them in rank, even though your GPA has been increased.

For a person with an incomplete set, their rank will slowly increase as they add coins to their set, raising their Set Rating, even if their GPA stays the same or is slightly reduced.

Strong suggestion: For other sets, determine how much you’re comfortable spending on each slot (or a group of slots). As you add coins, just be satisfied at whatever Rank that puts you. Don’t spend more for a slot than you’re comfortable doing just for the purpose of moving up in rank. Enjoy and have fun!!! That’s what our hobby is all about!

If there are sets missing coins and they are above you in rankings, it is likely they not only have higher grades, but perhaps more importantly they may have higher grades in the more difficult coins with higher weightings.

At the top of each set page there is a blue set composition button. If you click on it, you can see if some coins in the set have higher weightings.

In a set like $2-1/2 gold Indians, the 1911D has a weighting of 8, compared to a 1908 with a weighting of 1. If someone has a high grade 1911-D, it is possible for them to be missing a 1908, for example, and still be ranked above a set that is 100% complete, but with a much lower grade 1911-D.

The coin weightings can really matter in set ratings and rankings in the registry, in addition to set completeness and coin grades alone.

This answer should be pinned since PCGS doesn't make it too obvious.
