@konfirmed How are the queries coming along?

[mel-ada]

I've added a query list in the README, this is taken directly from the Metrics section in the linked planning doc!

I've removed this section from the PR description and replaced it with the README since it is mostly overlap. Leaving it here for reference:

@mel-ada are so these are not additional metrics that need to be queried? But fully covered by what is listed in the description above?

@25prathamesh @konfirmed How possible is it to have the queries written and added to the spreadsheet by the end of the week (Aug 12th)?

Also i see that you're adding multiple metrics in one sheet:

Please put each metric in its own sheet, with the sheet name being the same as the query file name

HI @foxdavidj @mel-ada @konfirmed @siakaramalegos

Thanks for the feedback I will put each metric in its own sheet, with the sheet name being the same as the query file name.

@konfirmed has already committed queries for the "What is the web getting right? - Priority hints" section, he will update data in the sheet

4 queries are still pending from Antipatterns Section which are LCP Element Resource Delay, TTFB by Category, Domain Sharding, and FID Double Tap to Zoom Disabled

I am already working on TTFB by Category query which I will commit to in the next 2 days, having limited time during weekdays I will not able to complete the Rest of the 3 queries by 12 Aug. I will try to finish them on 14-15 Aug.

@foxdavidj Yes, all queries needed are captured in the PR description. This comment is the original PR description and can be disregarded, it's for reference incase the analysts still needed it.

@konfirmed @25prathamesh how can I help? We need to wrap this up ASAP so @mel-ada can write the draft, which is due in a couple of weeks.

I've added the remaining queries, tidied up the results sheet, and added charts where applicable. Some metrics have a single value for both desktop and mobile, and these work best as simple "big number" figures rather than charts, so I didn't make any.

Let's get the PR merged and iterate on the queries if needed. @mel-ada PTAL at the results sheet and let us know if you have any questions. For some of the more complex results I added some analyst notes in the form of comments and highlighted the cells in yellow.

Sorry for the delay, hopefully it was worth the wait as these results are super interesting. Looking forward to reviewing your draft!
