If you look up at the stickies above there are descriptions of staggered nutrient additions. Pretty much it is adding nutrients and oxygen at staggered steps. I have used it on the last couple of meads I have made and it dramatically improved the primary fermentation, and from the samples I have tasted so far reduces a lot of the off flavors and conditions the mead much faster.
