once i twigged onto a few ideas about it, i wasnt even looking at the pics when i was answering. i think if i did it again id get an even higher score without looking at ANY pics, although it doesnt hurt to look at purdy women (and paris hilton) (",)
what i realised is that almost none of them are 32 anything. so you can reduce the guess to 50/50 straight up. many of the others are the middle size of the 3. when i next get time ill try the experiment...
