I'd love to see some stats on page load times etc.
There's a lot of repetitive debate on HN about JS web apps slowing things down and I'd like to know if the effects would be as bad if you could use the latest browser tools unpolyfilled.

Feels like you should make that the start of the blog post and cut it down massively, so people know it's not worth bothering with?
This isn't like statistics in a political poll where there is an expected margin or error, when it comes to logging sites you absolutely know everything about your users in regards to browser, operating system, and even the hardware (sometimes).
3% of a million is 30,000, 3% of 500,000,000 is 1,5000,000. An absolutely real chunk of users that can produce real value (for Instagram, ad dollars).
Why would there be a margin error at all? How would it be introduce? A large portion of crawlers masking themselves? I mean it's possible, but I do not know if that's enough to throw off proper logging.
Unless your initial page load is taking like 10 seconds, a human wouldn't even notice. And if it is taking 10 seconds, well, then you've got better things to fix.
That's not an actual improvement. That's just noise.
Imagine you lower the grip on everyone’s tires by 3%. Most people wouldn’t notice, but for a few people it will prevent them from being T-boned when they wait too long to brake for a red light. That improvement would be measurable if your data was good enough. I’m not saying optimizing your website is important like preventing car crashes, but it’s an illustration of how a small change can lead to a measurable improvement.
