📊 Trends

Unresolved error reports stacked by recent month
Total open production error tasks, by month

The overall increase in errors was relatively low this past month, similar to the November-December period last year.

What's new is that we can start to see a positive trend emerging in the backlogs where we've shrunk issue count three months in a row, from the 233 high in October, down to the 181 we have in the ol' backlog today.
