Hey, well the highest I got was 20 in a row, but I think I'm starting to see the trend in the way the graphs differ. The hard to guess ones are the ones that are spead out more. They are calculated by an equation and a strong corelation means that the relationships between the data are quite reliable(trying hard not to quote the text :-) )
The most suitable data are ones that compare the results of different things (so I'm not an english major) Like comparing student marks. Or the time which a group of people take to right an exam.

Anyway I was wondering how you other guys did?
