OK, the +5 was not the quota addition number. Freshman quota was 83 and upperclass quota was 5 which is stated as 83 + 5 for a total of 88.
Now, the reason some groups received more quota additions is that quota is based on the number that will place the most women and have the most chapters make quota (freshman quota). The computer program runs several options and settles on one. So it may be that one group would only pledge quota and the remaining groups would get quota additions.
