so, while the washers compressed your spring (and reduced amount of available travel) you didn't change the force required to compress the spring.

Hmm, I have always assumed that as a spring is compressed resistance to the compression increases, but I understand what you are saying. My relationship with springs will be changed forever.
 
My initial observation that the oil pressure at idle has increased a bit with the new spring seems to be true after a bit more running time. I will be changing that spring in all my engines and in my friend Tony's car.
