Avions Robin Service Bulletin No. 8 Rev. 1

Avion Pierre Robin Service Bulletin No. 8 Rev. 1 gives the following weight ranges that the all moving stabilators must balance within.

Weight Ranges for all-moving stabilators
  DR 220-221 DR250 DR253 DR300-400 DR1050M
DR1051M
Mini (gp) 480 830 530 540 830
Maxi (gp) 720 1110 770 800 1110

These ranges are found by adding weights to the end of the stabilator balance arm until the stabilator balances in the horizontal position.

As the stabilators appear to be the same size and construction on each of these aircraft types can anyone tell me why the different ranges are given?
