My last point was that the additional (and extraneous) water added with the sugar will dilute the entire batch, instead of just acting as a vehicle for getting the additional sugar into the beer, therefore you should only use as much as you have to.
BTW - I got CRAZY attenuation from my WPL 566 (Saison II platinum strain) - using this late sugar addition. 1.069 - 1.006 = 91% apparent... WOW.
