But the peak then lower peak could be variations in a noisy process (which LOD clearly is). If you look at the graph w/o the last 5-10 years, the downward trend is less pronounced because we don't have the 'lower lows' that the whole graph seems to show (I say "seems" to because I always hedge when looking at something this noisy). But it does seem like leap seconds are about to get super-duper funky for the next decade if we don't change how we cope... Of course, my views since 2000 are best expressed by Cato the Elder's speach ending catch phrase: "Carthago delenda est" Furthermore, leapseconds must die. Warner
