Not really, it's just a guess. With LPC the maximum possible residual could be much larger than with the fixed predictor if the coefficients were chosen randomly,...

In the precompute_partition_info_sums_ function, instead of selecting 64-bit accumulator when the signal bps is larger than 16, revert to the original approach based on partition size, but make room for few extra bits to not overflow with unusual signals where the average residual magnitude may be larger than bps. It slightly improves the performance with standard encoding levels and 16-bit files
