Is this some kinda joke? "Normal" boiling point is the boiling point at atmospheric pressure. Most of the world uses 14.7 PSIA (760 torr). For whatever reason, petrochemical & nat. gas industries use 14.37 PSIA (743 torr) as "standard" atmospheric. If the liquid is observed to distill between 206 C and 207.5 C (402.8 - 405.5 F) then the "normal" boiling point for at least one of the constituents is 206 C. Uncertainties: vapour/partial pressures, instrument calibration errors, minimum detectible level of observed distillation, how many beers the night before, and so forth. You answered your own question.
