Yes, of course, this is the sum of all statistics from all nodes, meaning I consider all nodes as one big node for myself. The only thing is that the same payment can go through two of my nodes, and thus the statistics will show double the amount. This usually happens when the path to the recipient's node goes through only my two nodes. But I can't determine the amount of such double or possibly even triple payments here. More precisely, it could be done with some degree of probability by taking into account the payment transit time and the hash of preimage. But I don't keep such statistics.
