As I suggested elsewhere the first step to familiarizing yourself with a run is to fully seperate all of your marbles from a run into the different color families. Typically my steps include first into larger color families, next into specific different color families, and for this run separating the lutz swirls out within the specific exact color combo. After you have them fully broken down, match them up with each numbered group and label them. Even as an investor, it’s possible you might be missing a variant.
