Instance boosting ("not working as intended") is faster then Questing, sry.

Also the beauty of my method is that that from 30-60 you only need to instance boost TWO toons, not four or five. So exp is about double from 30-60 for the two as compared to four.

You cannot quest 5 toons from level 30-60 FASTER then instance boosting TWO toons from level 30-60, with a level 70 or 80.
