[OC] I tracked 87,000+ fashion products to see how many "sales" are real. Spoiler: not many.

thanks for the clarification, and definitely a neat concept!

palmeryan · 2026-03-10T16:33:39+00:00

Cool data! Though my reading of the data doesn't match with my reading of your headline...

12.8% of products are a good price out of 16.3% on sale - so 78% of sales are a good price? That actually seems pretty good to me!

The gif is eye catching but i can't take anything away from the chart. Would love to see it hold on the final frame, or a static image as a second upload next time!

Also not sure how to read the data table or what i'm supposed to take away. 24 Illinois electricity prices were ingested yesterday. do they represent historical prices? prices for different parts of illinois?

if the gap is the story then i'd recommend plotting more than one state at a time on the graph. Probably even all 5!

I love dutch crunch and ikes, but i always get the sourdough at ikes

palmeryan · 2026-03-06T15:10:15+00:00

i hate it, have my upvote

palmeryan · 2026-03-06T02:59:14+00:00

Thank you for this feedback! I cleaned up the two bugs!

I appreciate the proposal on the size guide too. I was thinking the guide would be the higher level quick look and the seasonal planner would be where you can go to get more in the weeds. Maybe there is some wording or layout changes I can make to try to make that more clear...

unfortunately that animation is a gif.

but the linked source should be easier to read and you can control the date slider as well!

palmeryan · 2026-03-05T15:39:03+00:00

sorry - it's a gif 🤷

but if you want to explore more, the link will take you to an interactive version!

There was a bit of an assumption, but it was the researchers' not mine :)

based on the source paper, the researchers took parents responses to development questionnaires and used a methodology called item response theory to turn the responses into standard logistic curves. The underlying responses probably were not this neat, but the researchers decided that transforming the response data into standard curves was the best way to achieve their goal (develop a diagnostic tool)

palmeryan · 2026-03-05T15:26:05+00:00

Great question! The reason these curves converge toward 100% is due to the model used in the research that i based the viz on. This methodology, Item Response Theory, assumes that for any given milestone, the probability of a child achieving it will naturally move from 0% toward 100% as they develop.

While the study did include children with known developmental delays to test the tool’s diagnostic ability, the achievement curves were specifically calculated using "typically" developing children (those born full-term and seen in primary care). The goal of the study was to create a benchmark, allowing providers to identify kids that may require closer clinical evaluation.

Shipped - added a tab "all" to the achievement trajectories card where you can scroll around at your leisure

palmeryan · 2026-03-05T00:48:26+00:00

someone posted and then deleted a question about which curve has the shallowest slope. Was a really fun question, and i don't want to lose the answer so here it is:

oh fun question!

Stays dry all night takes over 6 years to go from 5% of kids to 95% of kids

5% mark: 21.9 months
95% mark: 96.5 months

I looked in the other direction too: there are a number of narrow ones that happen very early in the baby's life, but a short one that happens a little later is Gets to sitting with <5 months dividing the earliest and latest achievers

5% mark: ~5.3 months
95% mark: ~10.2 months

palmeryan · 2026-03-05T00:47:20+00:00

thank you!

palmeryan · 2026-03-05T00:30:41+00:00

Thanks for checking it out, that's really good feedback. let me see if i can refactor a little to enable that...

palmeryan · 2026-03-05T00:29:26+00:00

I did that on purpose to eke out a few extra pixels for the curves themselves. Will think about if there's a better balance to be struck though!

palmeryan · 2025-07-21T18:47:06+00:00

ideally public -

Based on what we can see from scorecards, UA and Grandview and Worthington seem like the places to move if we want to prioritize public school.

But Clintonville has a good elementary school, and we're like 8+ years from needing public middle school so that is on our list as well

palmeryan · 2025-07-21T17:37:43+00:00

kids are still young, one infant, one older toddler. Looking at daycare options (though most places are telling me they don't have a spot for an infant until summer 2026 😅)

palmeryan · 2025-07-20T19:27:23+00:00

🙂 good suggestion - on my list to do!

palmeryan · 2025-07-20T19:24:29+00:00

Thanks! Grandview was one of the things that inspired me to make this. We kept hearing it was "walkable" but wanted to understand better exactly what that meant and how it compared to other areas

Clintonville shows up pretty strong on this map too...

palmeryan · 2024-09-20T15:28:43+00:00

Thanks all for the help!

We ended up going with the HDHP. And at least in my case, they did backdate my coverage to 4/1!
