Seat tubes are tend to be thick at the bottom, close to the BB. They tend to be thin at the top, near the seatpost. See Reed Kennedy's compilation of tube measurements <https://docs.google.com/spreadsheets/d/1XeS2nJhBPSDRbqgG1-F2VOI_vK1QZnZmysARDJWyGps/edit?gid=500288468#gid=500288468> for some Riv and other examples (No, Sam H though, unfortunately). Hope that helps.
