The VWAP since Feb 2 is $1.6482. I have the figures if people want me to post them. ('People' as in 5 or more)
When we had the Japanese scare, the SP dropped to $1.55, which at the time was exactly the VWAP from Feb 2 to that date.
It's a fair guess. I have the same figure in my head, give or take 5%. Only takes another big red day on the ASX to spook the herd.
