Yes i agree they can be within 3 lbs, that is 3 lbs either way up or down,. This is not acceptable to me, ALTHOUGH they are a bargain. Landrum dyno test and marks EVERY spring, so you can order a 212 lb. or a 277/lb. Draco makes a great spring, but they are SO expensive. The other problem with these springs and others is they have the rates spread out, 200, 220, etc., and if you want lets say a 220 and a 250, you have to mix brands. Again they are a good buy, maybe on dirt spring rate is not that critical. This all relevant to what it is you are trying accomplish and what level you want to race on and of course your budget.
