The daily summary is updated using the total maxima and minima provided by the accumulator. Therefore, if I rebuild the daily summary from the archive table, information may get lost.

If I fix some single readings of some single observation type, I have to rebuild the daily summary. That's the normal procedure. Of course, for the observation type I changed data, rebuilding the daily summary is necessary. But the daily summaries of the other observation types should not be touched because of the possible lost of information

Is there a way to rebuild the summary of one observation type only?

There is no way to do this now (other than by hand), but it's a good idea. I've often come across the problem myself when fixing bad data.

That's a good Idea, I also run across this from time to time. So far,  I ran --reweight and changed the minima and maxima of the bad oberservation by hand, if applied.

Nevertheless, tightening the rebuild to a single observation type could still lead to loss in precision. I'd implement it in a way, that the mins and max' are only touched, if the rebuild mins and max' are beyond any existing values for that day. Also, a reweight could touch mins and max, if new new values are beyond existing mins and max'.
