    "456543": "I'm confused about time to failure and the structure of the data in general. Each training file has 150000 records so I assume that each 150000 record chunk represents an observation in the training data. For each training observation there are 150000 different values but we are supposed to predict a single value for a 150000 record observation in the test set. Are we predicting the average? I'm probably missing something simple since nobody else is asking this.",
    "456562": "The failure time, y, has been pretty much linearly interpolated from the beginning to the end of each earthquake.\n\nA 150,000 sequence only represents 0.0375 sec span. \nConsidering an error of 0.0375, it is really nothing, for the best LB scores are still revolving around 1.5 sec error.\n\nThat's also why the starter kernel uses the last value in the sequence as the single one outcome value.",
