Yes. But I seperate out the math from the time to weight and equal each part. Today we are pretty lucky. Most Pistons and rods are now well within a gram. So you are really just making sure something from a different run didn't get boxed together.
Once you have the big end, pin end, piston, rings, pin, pin retaining clips and a rod bearing weighed, you take about 5 minutes to add up the bobweight.
