Well you are in luck. No video but images of analysis. Hedgehog plot of normal vectors, they converge to flat at stem base. Hard to see since the stem/dimple share space.
Confirmation of immediate angle at stem base
Slope plot. Green being 0 degrees from up vector.

Use an email relay, and don’t enter many personal details. While this stuff is invisible to general users, marketers can purchase a paid linked in that allows gleaning that data and making call lists, so it will have your name, email, phone number, job description etc. This is fine if you hope somebody calls you for a job, but it also gets in the wrong hands and you get spam on your phone and email

Yes for sure, a farmer or artisan dealing in smaller volume knows their costs, and will deal for bulk buy etc. Modern corporate sellers know their fixed cost of procurement, warehousing, profit required, and logistics costs, so the price is the price…unless you can deal at the upper corp level for huge buys
Some people don’t quite get pricing and that they seem to want to hang onto their junk (they are selling) rather than let it go for a reasonable price.
One guy had a B/G router on Craigslist for the price of a new AC/X router. I sent a helpful message “hey these sell for $5 because they are obsolete, at your price nobody will buy that except a grandma that knows nothing about WiFi.”
He replied with a tirade of nasty insults, that I ignored. Few days later he emails against asking if I want it for $10.
I replied that I don’t want it , it is obsolete, I was trying to help so you don’t sit on it without a sale. And he replied with more swearing and insults.
3 months later I see it still for sale, and still too high. So I could not resist a little “I told you so” message.
