Corrections first
If a figure here is wrong, or right under conditions the entry failed to state, that is the most useful message you can send.
Corrections
Say which entry, which figure, and the condition under which your number was measured. Cold or at equilibrium, loaded or unloaded, at what reach. A figure without its conditions cannot be checked against the one printed here.
Suggestions
The file grows by mechanism, not by news. If something in a cell routinely surprises people who ought to know better, it is a candidate.
