There are currently at least 2,000 SNs per the last known contacts from the now defunct unauthorized storjnet.info … SNOs are probably only going to post “positive” success results, especially on threads such as this one. A prior post of mine much further up included my thoughts on why this particular metric is a poor metric to judge an individual node’s performance. It’s a relative measure of the ability of a given node to catch data, but the top level measure itself leaves out most of the differentiating factors – most of which are not under the control of the SNO.
My own success rates hover in the low to mid 80% mark. And I believe --I haven’t re-checked threads-- that I’ve seen at least two or three posters on this forum list success rates in the mid 60s. And your own analysis above clearly states the reality that 90% success rate for a particular node necessarily means that another node will have a 50% success rate.
It’s impossible for every node to have a 90% success rate, and the slower nodes are likely to be home networked and geographically far from satellites.
A home connection is certainly fine. However, a typical home scenario includes significant risk of hardware failure and electricity outage. Both of these risks combine to exclude – in the long view – most home built node operators.
The most profitable scenario is a data center server running multiple services on regularly maintained servers. In such case, the data center is recovering a little more profit from the sunk costs of the hardware. It doesn’t cost much more to run a Storj node on a server that is running 50 small web sites simultaneously…
