... wildly wrong. This is just one example for these tiles. If the highest is
$3.19 then the average cannot be $10.60.

Seems to be an issue for Trans-Red, Trans-Yellow, and White (left side or right)
at least. 6-month sales avg looks fine.

I think this same calculation might be reflected in the Price Guide. Of course
current items is almost always higher than 6 months but is it this much higher,
ever?

There is a German store that parts out sets and list all the items at the same
high money amount $$$ then a day or so later it changes the prices of those items
to be on the high end of the current PG. Maybe the PG autocalculation is cached
for some time, IDK if it is just a few minutes or some hours, but I think this
is what is happening.

That makes sense if the averages for a given part are only calculated once per
day. I've not run across this issue before, but it seems like Price Guide
manipulation. As in, if other stores use the regular current average price when
parting out, they'll accidentally price at least some items higher than they
ought to be, making the store that does the initial price very high but later
lowers it look like they have low prices when they don't.
