Hi Hank, Thanks, and fair question. Those two numbers measure different things. "Most Observed AS-PATH" counts exact full paths -- here "24482 35280 378", seen by 11 peers. The edge labels count how many peers cross that edge. The 25 peers on AS1299 -> AS35280 are split across several different full paths ("6830 1299 35280 378", "3491 1299 35280 378", ...), which is why that 25 never turns into a single winning path. Each peer reports the path as it saw it, so the leftmost ASN varies from peer to peer -- 259 unique paths from 349 peers in this snapshot. But you're right that the red highlight oversells it. Painting a 3% path red next to edges showing 25/18/15 makes it look like the "main" path, which it isn't. That's a display problem on my side. The computation stays as-is; I'll rework the presentation early next week -- most likely only highlighting when the top path actually has a meaningful share, and labeling the rest more honestly. I'll share what I come up with here. If you have a preference for how it should read when the winner's share is this small, I'd appreciate your take. Thanks again, Matin
