My statements don't flow well, so let me try and clarify.
-You get 80 points to spend on ability scores
-You may get more points later, after you turn in your characters
-the mins and maxes listed take into account that a gnoll could have higher or lower than normal and into account your parentage
-do not make adjustments for the gnoll pluses and minuses
-you may add the +1 to a score after your 80 and whatever else I give you, but you will do that later
