You can make something quite bad on average, and that's okay, you just have to be able to filter out everything you don't want and keep what you want. When CPUs are manufactured, this is what they mean by the "yield". It's the percentage of the product that can be kept, with the rest of the wafer discarded.
Chef's Gallery had a scene that actually shocked me a bit -- this award winning chef was making this deep-fried puff thing that was absolutely perfect. They showed his process, which was to make dozens of them and then plate just the best one for the customer. He never had a knack at all for making them perfect! He was just throwing out 99% of the puffs that he made, using the same technique as anyone else would.
You just have to change your perspective: You're the product. You're the deep fried puff.
If you're an outlier, you will be discarded. You're the bent piece of framing. You're the slice of the silicon wafer that failed the test.
Nobody feels the slightest bit bad about rejecting a faulty product on the production line. No tears are shed. No phone calls are made to the product to see if there's anything the manufacturer can do to fix the situation.
This is Google and by extension YouTube in a nutshell. They're an advertising company manufacturing ad impressions and ad clicks. Viewers are their product.
Viewers on 1 Mbps or 1 Gbps are equally outliers. Both are too weird to cater to, less than optimal, unpredictable, difficult to advertise-to viewers.
Rejected.
