I would say that you definitely need more than 3/4 cups of corn sugar for 6 gallons of home brew. You are increasing the amount of beer by 20% so the corn sugar should also be increased. I would say 1 cup should do the trick. 1 1/4 cup would probably still be OK as well.
When you talk about the beer having a certain carbonation after a week and a half, my brews have always taken about 3 weeks of bottle conditioning before they are at their peak. Your third batch will probably be more carbonated in a week or two.
Also, make sure you stir the beer well to evenly distribute the corn sugar in the beer.
Hope this helps.
