Out of curiosity, what is?</div>
people typically adjust their technique for a more advantageous position when they are pulling from a rack, so if you start at the knee, you get people who are pulling much more than they are capable of from the floor and the carry over ends up being worthless.
If you are pulling from the rack, make it below the knee for the most part. Some time spent above the knee is ok, but most of it below the knee. if we take Louies observations that if you are pulling >10% more than your max pull, on the racks, its not really worth it. (altho Chuck V has rack pulled >1000 and his best dead is in the mid 800s or so).
To get specific loading, you can add bands to the pull, so you over load the lockout, or you can add in chains which do the same thing in a different way. Reverse bands are another option.
You also have to strengthen the entire muscularture in the upper back, all of the core shoulder muscles should be strong as hell, as they are the ones that will control the scapula position and ultimately the lockout position.
Heavy rows, facepulls, multiple angle shrugs (upper/mid/lower), chins etc.
Hip work is also important, to get that last little bit of lockout from the hips, glute, hammie etc. Romanian deadlifts, glut/ham raises, reverse hypers etc.
Technique is vital as well, but its relatively individual specific (torso lengths, limb length etc.
