Yes 43.39 is the average of the 34.60 and 52.18 - in this case it took an average.

Edit: the oddest thing is the 25.89 came in on Sept 30 but then got 43.39

If min_quorum = 2, normally 2 results is used then validated, and in this case the smallest of the 2 claimed credits decides the crediting. LHC is using min_quorum = 2.

If min_quorum = 3 or higher, atleast 3 results is used then validated. In this instance the highest & lowest claimed is discarded, and the rest is averaged.
Seti@home is using min_quorum = 3, so normally the middle is avarded.

But if one user misses his deadline but returns a little later, a new "result" was immediately generated then passed the deadline and sent out. With backlogged or offline Validator it's therefore possible 4 or more results is waiting for validation, and you'll get the average after highest & lowest is discarded.

Here is an interesting WU result.

It ended up being sent to 7 machines.

The first 3 times no systems returned any results, then it had to be sent out again after the deadline passed...and one of those 2nd stage machines had download errors..so yet another.
