I'd much rather have 0.11 to 0.25% average packet loss over a 3 to 24 hour period than 2-3%.

The starlink experience is overall superior at present from a subjective user point of view.

... and I think that this last sentence is the most important one.

My current Internet is a 4.3 mile WiFi link to a tower, which has a
wifi link to another tower, which has a wifi link to the POP with
fiber....[0]
There is some correlation between what smokeping shows and what my
subjective experience is[1],  but it's not absolute. Hearing "this
feels better/faster" is sometimes more useful than "this graph shows
X".
Yup, the Starlink graph showed some spikes of 280+ms, but the general
latency looked low. Goodput might be great, or not -- but the
important bit remains "overall superior at present from a subjective
user point of view."

[0]: Yes, I did the Starlink preorder the second it was available. No,
sadly I don't have it yet...
[1]: Usually poor. Especially when anyone else is using it...

I don't know how you can be embarrassed when you have a pretty solid
30ms ping constantly, and Starlink has jitter all over the place and
spikes as high as 280ms.

I'll take the DOCSIS3 system....

I thought I would post an interesting comparison between a degraded
DOCSIS3 link, of a carrier that shall remain nameless to avoid
embarrassing anybody, and a starlink CPE with a slight 1/12th tree
obstruction in a portion of its view.

First two screenshots are the docsis3, to its gateway and to a very
reliable hosted asterisk system in Seattle.

Second two screenshots are starlink, also to its gateway and to the same
destination.
