edit the Productivity comment after I've understood finally how the second figure is useful

-The events added above should be enough. Again. we only do the elapsed case. 
-Ask JaffaCake if it's OK that the "% of total elapsed" in +RTS -s is actually the CPU time divided by elapsed time, not elapsed divided by elapsed.
+The events added above should be enough. Again. we only do the elapsed case, so we'd show elapsed/elapsed, while the figures above
+are cpu/cpu and cpu/elapsed. JaffCake thinks the latter mixture is OK. However, it mixes the productivity
+of CPU mutation vs elapsed mutation with the productivity of mutation vs GC. In this light, out figure will not be that bad, 
+because it's consistent, even if not as accurate as the equally consistent first figure above. 
+
+BTW, the fact that the second figure is higher (I can reproduce it), shows a problem with clocks or some other problem.
+I'd guess the elapsed time should always be higher than the CPU time, shouldn't it?
