Great website, by the way!
Jack,
Thanks.
Yes, measure from the top of the stem(the bolt that goes in the steerer) to the center of the seatpost while holding the tape horizontally. This will give you the "effective" top tube measurement regardless of the tt slope. This is also the way most manufacturers measure tt length and the main measurement a custom builder uses to tailor a frame to fit.
