I don't believe so.
My chapter sort of did what you're describing... We started out as a local sorority, well below total (total=80, we were at 12 counting my pledge class). We thought 80+ was too large to really bond with everyone in the sorority, so we made a conscious decision to stay below total. AEPhi was fine with this.
We actually had a weird way of setting quota. Quota was (# women attending pref) * 22% for the other sororities or 12% for AEPhi. There's a stipulation in the rush rules that the percentages will be re-analyzed if AEPhi makes quota.
Even so, my chapter has never made quota or even come close to total.
