121 of 189 fly taste targets keep their class count preference after any one recorded sensory input is removed

We tested how many sensory cell deletions can remove the leading taste class in three public connection tables from one female fly. The leading class is the class with the most retained synapses. Of 189 targets, 121 keep a strict lead after any one connected sensory source is removed. Of 152 targets with at least 80% of their retained counts from one class, 46 fail this test. All 46 have just one recorded source, so deletion erases all recorded input. The other 106 pass. Across all targets, 22 can lose their lead after one source loss while some input remains. An exact count margin gives the test and the minimum number of source deletions. We supply derived edge and target tables, code, hashes, an independent deletion check, and a figure. A bounded missing-count test and stricter edge thresholds show sensitivity to the retained graph. These results describe count allocation in one curated connectome. They do not predict neural activity or establish a rule across animals or behaviors.
