	So I thought that we basically have around 50Mbps “shaping-capability” on the wndrs which hew can distribute between egress and ingress, but if your analysis is correct wouldn’t that mean that shaping egress is cheaper? (Not that this has much relevance in the real world due uplink << downlink asymmetry the ISPs push onto us endusers)
