In Automatic Speech Recognition (ASR), the Real Time Factor (RTF) is defined as the ratio of processing time to the duration of the audio input. Given a list of audio chunk durations and their respective processing times in a multi threaded or parallel environment, calculate the overall RTF. Assume the total duration is the sum of the audio chunks, and the total processing time is the maximum time taken by any thread if processed in parallel, or the sum if sequential. Implement a function that calculates the RTF for parallel processing, where the total processing time is determined by the longest running chunk.
