Confused - 25m shares traded in one hit?, page-14

I've been using Iress on and off for years. Can't recall when I first noticed the Top20 oddities. It seems that Iress (my version, at least) updates its Top20 list each month. I use the term "updates" loosely. What I mean is that the date of the list is usually as at the end of the prior month, but I have seen it remain "sticky" in terms of not reflecting known changes that occurred throughout the month when the EOM cycles around (i.e. according to various Form 603/604/605s for example). The short answer is I'm not sure how reliable it is and how frequently it actually updates and just how completely it does it. Given my activity, I don't subscribe every month.

PS. js2010copper, isn't your $0.001 the same as my 0.1c? I'm guessing there was another point I prolly missed...
