Might I ask why you built your own, knowing there was an almost identical offering in place for years? For example, did your different choice of releases cause a statistically significant shift in arrival times? I imagine you've done analysis comparing your approach to theirs.

I built my own because their design, and I mean literally the way they visualize the data, isn't very good. Or rather, it's not as good as it could be. They even updated the design a year or two ago and all they did was give it a coat of paint, rather than rethinking how to best visualize the data.

I love your approach :) it's very helpful!

That's a great reason! I agree their design sucks and yours is orders of magnitude more usable.

It's just too bad that you have to re-collect the same data. N historically up-to-date data sources for N designs is just unscalable.

Indeed. Maybe I'll post the data on GitHub or something.
