I would wager that even some pre-eminent bike builders can not say with absolute certainty that if bike A has a downtube with wall thickness x it will deliver ride y to a rider of weight z. There are some general assumptions that may be made. The more experienced the more fine tuned those assumptions become. In the end, however, factors such as hub, rim and tire choice, saddle used, road conditions, etc. will all play rolls largely out of the frame builder's control.
