The drum size assumption is wrong.

My objective was to show approximately how many turns would be needed. Something more will undoubtedly will be needed to obtain proper and desired operation.
I was also trying to smoke out something more useful than "you're wrong" from someone named Kinch.

Adjust to fit, paint to match.

I am of average height and strength. I am already 65 and still have all my body parts in good shape.The first try got me within two quarter turns of the right tension to fix my door. Those springs were not designed for supermen with super skills to install, just average guys like me and most people. Those technicians would need at most a high school education and a few on the job practices to learn how to install garage doors. If they can do it so can you. Just exercise some common sense regarding safety. You would know by feel if you are over tensioning the spring and it would take Hercules to break one. Its more of a problem to get enough tension than to over tension. There was a time when a curious kid would take apart everything he could put a screwdriver to and then put it back together. Later on one learned to rebuild one's car, fix the appliances around the house, etc. Many of you guys seem to need to call a specialist to change your flashlight batteries these days.
