I meant that since we are dividing by weight and absorbweight 
` weightedDelta = delta / weight;`
and
 weightedAbsorb = (delta - gslimit) / absorbweight;
where both weight and absorbweight uses += gi.weight values so if one is checking for >0 
then to be consistent, in my opinion, 
other one should be same or absorbweight also probably should check !=0.
