Instruction: The given data presents various performance parameters of machines (named 'FTX01', 'FTX04', 'FTX05', 'FTX06') like 'yield', 'cycle_time', 'uph' (units per hour), and 'output'. You are expected to summarize this data, providing a separate section for each parameter. Look for patterns like which machines are performing as expected, which are doing good, and which ones are showing an increase in spread, suggesting a decline in performance. For 'cycle_time' and 'uph', identify the machines that are operating within normal parameters. For 'output', note the production percentage and actual output for each machine and interpret this data in terms of their performance and efficiency.
