Which would still be faster than libaom, and would make more exhaustive use of HEVC's features. At very low bitrates, maybe another 10-15% reduction in bits @ quality versus slower.
Quality @ Speed is the name of the game here, and comparisons at orders of magnitude different speed aren't that applicable to estimating real-world advantages of different bitstream formats.
(not a diss at the OP; that data might have been useful for an internal comparison for just posting to Twitter. I just want to warn against premature optimism based on Excel RD plots).
