You are still not getting it are you. The point that I am trying to get you to see is that a 2:1, or any other vswr for that matter, can have an effect above and beyond the numbers that you are quoting from the calculator, and that additional loss have make a more significant effect on the final output power than tjose numbers. Or put put another way a 2:1 vswr may actually be something worth worrying about.!!

We are still talking past each other.
I am describing the losses incurred by a piece of coax cable under two conditions: matched, and with a 2:1 mismatch at the load. Those losses are independent of the characteristics of whatever device is supplying the RF and they are reliable and reproducible for any given length of coax.
You are talking about the effect of the standing waves on the exciting device which is a separate and independent issue.
Both affect the power actually delivered to the load but they do so independently of each other.
