One inch spacer, 50 pounds, 2 inch spacer, 100 pounds. I was think of two inches to show a larger value.

Look at your rear shocks. Set them for soft and push down. Notice how far they go down. Then set them for hard and push again. It is the same thing, you add more preload, thus the force needed to compress them without changing the shock length, just the spring length.
I think you are missing one thing. The spring without a spacer is only compressed 6 inches, thus the 300 pounds. A spring with a 1 inch spacer is already compressed 1 inch inside the fork. Pressing it down another 6 inches is actually compressing the spring a total of 7 inches, thus the 350 pounds, but the forks only moved 6 inches. You are not increasing the spring rate, but you are increasing the force to compress the forks. The key is, with the spacer you are already starting with 50 pounds, you cannot ignore that, it is part of the equation.

I think this is where things get murky...you say inserting a spacer makes things stiffer. That might be the case for a progressive spring, ...
