Actual sponge hardness? Hybrid MK etc

[Crillo]

Hi!

How come for example Hybrid MK (48) or Tronix ACC (47'5) feels so much softer than the stated hardness? I know that the top sheet i softer then for example Fastarc G1 (47'5) and older generation rubbers with thicker top sheet. But I feel that the sponge i softer as well. Enlight me please!

When playing you feel the combination of sponge + topsheet, you can’t feel the component separately…
