Sadly no, you are comparing a solid metal ball with a hollow plastic ball (different brands have different hardness, too).
What folks have to understand here is that there are multiple hardness standards out there, some of which are interchangeable/compatible. What some of us are attempting here is:
1. To figure out which specific standards are used by which manufacturers/brands here, and ideally how they make the measurement;
2. We hope to be able to reproduce it and make the same measurement with the most commonly used hardness scales;
3. We hope to be able to compare across different manufacturers/brands with a certain level of confidence.
Over the years, the last point has been attempted by various folks/magazines. It won't represent real-world scenario, but we don't care about feel either, which is subjective (whatever feels good for you is not the concern here). We want to leave that out of the equation. We want a simple number that scales linearly that can be compared quickly, which is exactly what a hardness scale does.
I understand what is trying to be achieved, and agree that 1 way of measuring hardness is needed, no differing scales or different measuring devices used for measuring TT sponges / rubbers. It removes confusion, or some of it. Takes away frustration. Some of it.
next up
speed - standard speed scale please.
spin - standard spin scale please.
throw - yep you guessed it standard throw scale please
grip …….., tackiness………etc etc
If you find a rubber you like and suits you, then knowing the numbers and say picking one of the attributes ONLY and improving that attribute or worsening that attribute. less speed, more speed etc makes things much easier, less frustrating.
Its a case of how many scales for attributes do you actually need??
And all this means diddly squat if you are playing in the wrong conditions, as you watch balls slipping off your bat left right and centre!!!! (mind you if your opponents equipment is less sensitive to the playing conditions, then the playing conditions are obviously right as far as they are concerned.!!!)
