Takeaway

Recommended or revised 8 times between 1902 and 2024 (first record 1902, latest revision 2011).
Both revisions whose previous recommendation had an uncertainty kept the new value inside the previous (expanded) range.
The current standard atomic weight is 114.818(1) (recommended in 2011).

Relative deviation from the current (or last) value, symmetric-log axis. Bars: uncertainty (expanded range); open circles: no uncertainty; orange boxes: intervals.
