There will be a curves for the efficiency of a tray with permitted vapour and liquid loadings. As a rule of thumb I remember (I hope correctly) that three real trays equals one theoretical ideal tray.
To 'roadkill' below. It is not actually true that each tray will be a theoretical tray at total reflux - inefficiencies such as entrainment, non perfect approach to equilibrium of vapour bubbles etc will still occur, however the material at the top and bottom will of course be much more pure due to the recycle not tray efficiency

I don't really get the question. At total reflux if I understand that correctly nothing is being removed from or added to the distillation tower. If allowed to run a long time at this condition all the stages would be the equivalent of a single theorectical stage no matter how many real stages you had.
