Springs are rated as how many pounds per inch they resist compression. Right?

Let's take say a 36 lb/inch spring and compress it two inches. That would require a 72 lbs of pressure - am I right?
Alternatively for compressing said spring a mere half an inch would take 18 lbs. Right?

I wonder why in the heck am I getting 15 lbs/inch read outs from my own selfmade compression setup for the above Luger 36 lb/inch spring?
I double checked everything. Twice. No obvious errors.

At maximum I had 33,11 lbs hanging there, that made spring to compress 2,17".
What gives?

Commentary most welcome - indeed.
