TEST readout_error vs "the average of these two errors": 160 of 5543 distinct measurements differ by more than 0.001 on the same measurement date; by more than 0.01: 18; largest 0.157; 50 qubits on 5 processors
     on qubit indices 16 mod 17: 141 of 160 (all qubits with that index: 318 measurements)
