The only problem with this bullshit thread, and I haven’t waisted my time reading through all four pages. Is that’s it is complete pony, the other thing is you may be “math smart” but you seem to be missing something here in all this, while comparing NYC with Mumbai.

The vast majority of people in Mumbai are generally poor and I wouldn’t say it see’s the same sort of in/out travel as NYC which is basically modern day Babylon (It is the heart of international trade) so I would expect the numbers to be higher in NYC with all the comings and goings with people in and out of the country etc.
Where there is more movement, there is more transmission and where there is more transmission = more infection.

Good luck with it anyway, it’s obviously something your passionate about,
Make no mistake this definitely not the most important thread you have ever written.
