This note uses techniques developed in Beams-doc-1925 to set an upper limit on the stability of the upgraded Tevatron BPM system over a period of about 19 weeks. The stability of the proton position measurement <40 microns for a typical BPM and <80 microns for the worst case BPM. Excluding two anomalous BPMs, the stability of the anti-proton position measurement is demonstrated to be <60 microns for a typical BPM and <150 microns for the worst case BPM. The two anomalous BPMs show jumps in the anti-proton position that appear to be instrumental effects; the properties of these jumps are recorded in this note. The cause of these jumps is currently under investigation.
