Yet another icmp results question: %loss and ???

Using basic bash scripting, I am trying to run ping/mtr tests to better understand the results.

I understand the basics and know that when I see %loss, yet see the next hop, it typically means that the hop is either having problems is more likely, icmp is being limited. If I can see the IP of the %loss hop, it still doesn't mean that I can tell if the hope is having problems or if it is being icmp limited.

The fact that I can see the next hop tells me that the path to the target is complete but what else can I learn from this test?

There doesn't seem to be any reliable way of knowing if a %loss hop is experiencing problems or is only being icmp blocked or limited. Throughput might be one way but that would mean having to know what the previous throughput was and again is reliably unknown if it is traversing the internet.

So my question is... IS there a reliable way of determining this short of knowing the hop owner and contacting them and how can I do it using a bash script.

If you can get to a hop beyond the one showing %loss, that means it is working but not responding to 'icmp' because you get to the next hop by going thru the one showing %loss.  If the one with %loss was actually down, I believe the trace would stop there.

Yes, that is what my question says but I am wanting to know if there are some ways of knowing reliably what is going on.

No, not with ICMP or traceroute.  You're seeing everything that is available with those methods.  Since those servers are not otherwise accessible by you, there is nothing else to get.
