| So, I'd like to understand how scientific the measurements are for parts,
as I have come across some variation in the weights for some parts that share
the same "mould" (part number anyway).
Is it possible to request that someone re-analyse some of these to assess accuracy?
This is regarding the main minifigure hips and legs.
970c00 - 1.18g
970c00pb0966 - 1.16g - black
970c00pb0861 - 1.19g - black
970c00pb0961 - 1.27g
970c00pb0444 - 1.18g
While I'm not an expert in ink weights and color/material weights, this seems
a bit suspicious. If it was an issue of colors, then all matching color parts
would have very similar weights.
People are paying shipping based on these weights so they need to be accurate.
I'm just wondering if this has actually been reviewed, for this part in
particular?

Weights and measurements are submitted by members so there is no confirming their
scientific accuracy. These weights are all well within a range that is unlikely
to affect shipping costs. If you feel strongly that any data in our system needs
to be corrected, you are free to submit a change request to update it.

Given that BrickLink is owned by TLG, there is some reasonable expectation that
the data regarding the parts would be shared. especially given this is a for-profit
company. Has there been any statement why data like this is not being shared
that anyone knows of?

The rule on BrickLink is that the catalog goes with the heaviest color / version
of an item under a given entry. This is to prevent undercharging on shipping
costs.
The data from the LEGO Group is for modern elements, and typically these are
lighter due to more efficient molding methods being developed over the years.
BrickLink will tend toward the older, heavier weights, so this new data is not
as useful for us as actual measurement.
The total spread in the parts you have listed is 0.1 gram, and without the outlier,
which may be due to the silver coating on the feet, we are down to 0.03 gram.
For the purposes of the instant checkout shipping calculator, 3 hundredths of
a gram is only going to make a difference when selling at high volume, and at
those higher total wieghts, the shipping bands are quite far apart.
More importantly, all of those weights were submitted by individuals who now
have a credit in the BrickLink system. Community involvement is more important
to us than absolute accuracy and standardization, because we recognize that it
takes a community to build the kind of catalog we all enjoy. The key is to get
more people involved and more people contributing, and in the end, that will
translate into the best catalog possible.
That doesn't preclude us from using LEGO data either. We can use it to check
submissions for accuracy, and we regularly do.

And those 3/100s of a gram per part are insignificant compared to the weight
of any packaging a seller is likely to use.

Thanks for clarifying on the data usage. I appreciate all of the responses. A
few have been explained or verified already. Especially where newer parts may
be lighter than previous versions due to manufacturing changes - yet are not
captured in a new Part #.
Its apparently all understandable variation, which is honestly surprising to
me. But I'm glad the community has put forth an effort to aide me in understanding.

970c00pb0961 - 1.27g
970c00pb0444 - 1.18g

This decorated version does actually weigh more:
970c00 (White): 1.19g
970c00pb0961 (Decorated White): 1.29g
|
Yep. And that is due to the dual molding process which adds more plastic between
the two colors.

Just checked this one and indeed the weight is on point at 1.16g

- 1.27g

| One of my dream features would be an alert system, where you could put a specific
alert on any entry in the catalog and everyone could search their inventory or
the catalog for items with alerts. So if something didn’t seem right but you
were unable to correct it, it would go in somewhere where the people who might
not see your forum post on one day will still see your issue. Your question
about the Mickey legs was answered this way, but it could have been missed.
I will soon be reshooting because I got one in a used lot, but
If we had an alert system someone would have tagged that picture needing a replacement
and I might have bought one to fix it.
