>Yes, you build up tolerance no matter what. Except drinking tea all day has way less drawbacks than drinking coffee all day due to lower overall concentrations.And this lower overall concentrations will produce a much weaker effect than the ones from coffee because of it's inherent worse AUC as we are literally talking about less quantities of the only pharmacologic active substance in both beverages.
That the duration of the substances in the body is the same doesn't matter (and 10-15 % is still more than significantly relevant) as what's important is the AUC. It's a quantitative issue as caffeine is a competitive inhibitor, not a qualitative one.
