Runza's nearest audiences span a notably diverse mix of subcategories — regional grocery, casual dining, convenience fuel, and automotive services — with no single neighbor pulling far ahead of the others. The shape is flat: the top score, Fareway Stores at 0.89, sits only about 0.04 points above the tenth neighbor, and the band stays compressed across the full set.

Tallying the top 10 by subcategory: three are Casual Dining (Perkins Restaurant & Bakery at 0.87, Bob Evans at 0.85, Pizza Ranch at 0.84); two are General Grocery Stores (Fareway Stores at 0.89, Hy-Vee at 0.85); two are Gas Stations (Hy-Vee Pharmacy at 0.87 — classified as Pharmacies and Drugstores — and Sheetz at 0.86); and the set also includes Scooter's Coffee and Yogurt (Coffee and Tea, 0.86), Best One Tire & Service (Automotive Maintenance and Repair, 0.85), and Arnold Motor Supply (Automotive Parts and Accessories, 0.85). Runza itself is a QSR, and no other QSR appears in the top 10 — the nearest audiences are shaped instead by casual dining, grocery, convenience fuel, and automotive services. That cross-kind spread, rather than concentration in any one subcategory, defines the cluster.

The flat distribution across grocery, sit-down dining, fuel stops, and auto shops points to an audience whose daily errand patterns — not a single category loyalty — determine what else they follow.
