I'm guessing this a bottleneck issue — would you be up for trying to run bottleneck's `nanmax` function on the underlying numpy array (`xdata.data`), and seeing whether that has the same effect?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1057335460
