If the cow is much bigger and her offspring finish faster; this means there could have been room for more cows in the pasture.
The problem with smallish cows is not so much the steers; but rather the heifers. A thousand pound cow has steers calves that finish out at 1000 pounds and dresses out at an acceptable 630 lb carcass. Her heifer calves are going too finish 100 - 150 lbs lighter and typically have a lot of waste fat. Most heifers become feeder calves NOT replacements.
Yes; a cow that is a little bigger than 1000 pounds will also produce a heifer of adequate size. Will 1100 pounds do ( it would give heifers 10 % higher carcass weight)? Surely 1200 pounds is enough, as it makes her daughters 20% larger
Rule of thumb is that a steer finishes at his mom's mature weight and his sister a 100 to a 150 lbs less. A thousand pound cow would have 1000 lb finished steers and 900 lb finished heifers.....not 1200 pounders unless you bred her to a terminal sire and/or weaned the calves to 6-9 months of good grass BEFORE sending them to the feedlot.
