The ls crank is 89mm, the gsr is 87.2mm, difference is 1.8mm of which .9mm is added up top. Think of it as .9mm is added to the radius of the crank.
The ls rod is 137mm, the gsr rod is 137.7, difference is the ls rod is .7mm shorter.
.9mm-.7mm is .2mm or .008inches, not very much. Show me where my math is wrong.
