Weeks 23-24 Summary                                                                                                          

Electrical Testing continued its slow and steady decline, dropping to its third lowest count for the year at 51% in Week 24, despite an upward blip to 55% in Week 23, averaging 53% for the period, down from the prior period's 56%.

Eight different devices which had a high failure rate in Electrical Testing, and two of those had a 100% failure rate.

Inspection results had a significantly better period, reaching up to 79% in Week 23 before crashing back down to 58% in Week 24, averaging 69% for the period. That is 6 points up from the previous period, but bitter-sweet with the high and low extremes.
