I think this is why Netflix came out with, but AFAIK, they're the only ones that have their own tool using their own infrastructure. came out with a test that simulates video streaming and gives a bit more information than a feeling, but it can only go so far, given that it isn't on the actual networks people are concerned with. 

Also, this doesn't just apply to residential accounts, but really anyone without a strong enough IT department to have their own test points to test to.

Totally see your perspective. I'd say that's pretty unique to your space though, given the majority of (domestic) fixed broadband customers don't have that choice. 

But completely understand what you are saying.

SLAs are irrelevant to customer perception, only to bean counters. 

Few to no residential-class services have an SLA whatsoever, yet they'll be the most demanding at any perceived slight. 

Stand by your SLA all you want, but if a customer's expectations (realistic or not) aren't met, they'll not only leave, but they'll tell everyone else how terrible you are.

I've visited friends and employees homes and found that while plugged in, a streaming service could not send a single stream at full resolution without buffering. It would be nice to show numbers (not just a feeling) that the other service could only deliver X megabit, while your service could deliver Y megabit.

Most SLAs only cover on-net services, I recommend having a good 
on-net server for testing purposes and knowing your immediate upstream 
and peer upstreams test points. I do recommend that most carriers have 
an iperf3/iperf2 test point. You may find your carriers have one as 
well, even if it's not listed in their support pages. 

I've found this useful when you suspect some problem, including 
a link hashing problem that only impacts a few flows.
