Rubber hardness, sponge or topsheet, or both?

   Hi everybody on the side of technicians 

When everybody talks about hardness, is it only sponge or the whole sheet of rubber?

In my observation, Tenergy 05 "feels" a bit harder than Tenergy 64 by the same hardness. Evolution MX-P is 37.5 in Japanese scale but it is significantly harder than Tenergy 64 (D37)

Another observation is the topsheet of Tenergy is actually softer than any ENS rubber, measured directly on it "skin" without pips. 

My question is: have anybody experimented the softness of different topsheet material of different rubber brands?

	There is no real "pro", "prov" or "NT" H3 in the market. Falco is not a booster
