can we trust the timings given to us by Google?
So far there has been a lot of corroboration from the webmaster community, so I'd say yes, we are looking at a good degree of transparency. The challenge for me is all those other little updates that Google mentions in the monthly summary without giving a specific date.
But at least they tell us what target areas they were aiming at. That's more than we used to hear about.
