Masu-Conjugation of honorific verb

Hi everybody,

I recently learned that somce hon. verbs are suppose to have another masu-conjugation rule.
Which says that the る turns into い instead the usual り.

E.g.
なさる -> なさいます

But now I just saw that the conjugation table (from Tangorin) of all hon.verbs use ~ります.
I.e.
なさる -> なさります

Though the example phrases use "なさいます".
But I just wanted to make it sure.

The conjugation tables were probably automatically created. なさいます is correct.
