The article uses the puzzling phrase "we thought we knew" to suggest that the radio-based measures of the big planets are somehow invalid, but does not explain why any combination of atmospheric features, observed for any length of time, should give a better estimate of the rotation time of the planetary core. He makes a convincing case that different atmospheric strata, at different latitudes, rotate at different speeds. It is remarkable that he finds as much consistency among multiple features as he does, but why should these supplant the radio-based measures?
