Dear bricklink development team,

Currently the "Part Out Value" page shows the value in average, which may not
be accurate if any seller posts an item with very high, or inaccurate price.

To better represent the part out value of a set, we need to add the following
additional metrics:
1. Standard deviation of the Average value shown
2. Median value
3. Breakdown list of all items with the above metrics for each item. Additionally
we would like to see the count for each item.

Thanks

Way too much attention is paid to average prices as it is. Just consider what
the average sold price is...

across markets/ countries

all stores big and small

stores that price fairly and those that charge add ons

all orders - single lot/ multiple lot

It is also dangerous to purchase based on part-out sold prices anyway as many
parts might have sold for an average prixe of X but in some cases there are many
100's of times of the part for sale than have ever sold!

Focusing on making the average "more accurate" is IMO a diversion and not a good
way of optimising inventory investment decisions. If it was just a mathematical
excercise to determine what to buy this place would be even more swamped with
inventory and prices would drop further.

I always vote no to these enhancements to averages for these reasons, I think
these average values mislead many.

Whilst your suggestion is very good - nothing is being done by the development
team to the classic site whilst Bricklink eXpress is being developed. So it will
more than likely fall on 'deaf ears'. An awful lot more needs doing on
the entire part out process on this site. The part out log should not be just
a reminder of the date when you parted it out - it should contain full details
of the part out. You should also be able to see what the 'new lots' will
be from the first screen - we need more flexibility in the initial screen especially
with remarks fields, as well as seeing what we have the item listed as etc. etc.
Lots to do - nothing will get done. Shame really as it is a very important part
of the site.

If you need this information you can get it, you just need to do it part by part.
However, it is probably way too much information needed for most people when
considering purchasing a set to part out. You also miss one really important
thing, and that is the trend in the prices of the parts. New parts especially
can have a very misleading six month average, as they typically start high and
drop as more people buy the set and part it out. I found it was always better
to look at the expensive parts of a set first, and check whether those are realistic.
You can find those quickly by starting a part out but not completing it.

It's not supposed to be a gold standard. It shows the average price of SOLD
items in the last 6 months and that's a pretty good guideline. It isn't
necessarily accurate to what you will get and it definitely isn't precise,
but it's a pretty good guideline.
