This read-write INTEGER (0-100), expressed as a percentage, sets the statistical confidence interval used when calculating the wearout and non-writable date projections from the short- and long-term averages. An admin can raise this value to get more conservative (earlier) projected dates for safety margin, or lower it for projections closer to the raw statistical average. For example, setting this to 95 would make the projected wearout dates more cautious than leaving it at a lower confidence percentage.
