The tough one is the node count. Because it's pretty hard to do, and it's never a very accurate thing. So that leaves room for biased accounting.
For example coin.dance is still counting Segwit UASF nodes but for some odd reason, they don't count BIP110 nodes? Sus AF buddy.
And kinda useless to me as I'm trying to keep track of the BIP110 node count from various sources.
As for BIP110 signalling blocks, it doesn't matter where I get the numbers as those are pretty hard to fudge one way or the other. So I'll stick to kilombino as I like the interface. Same numbers anyways.
I've been keeping an eye on various sites for a while now. The one I considered more reliable for node counts was bitnodes.io. And sadly enough, it went off line when it was showing around 9% of BIP110 nodes.
Now what I found interesting is that both Bitbo and Bitnod where both showing numbers pretty close to Bitnodes. But as soon as Bitnodes went off line, they both started to trend down and they have been at around 4% for a very long time now. Weird?
