Pummeling Style and Hardness - RAW or RAI?

[Kiesman]

I've been doing some google-fu for hours now trying to determine whether Pummeling Style works properly with sundering and item hardness. RAW, the text for Pummeling style states:

Pummeling Style wrote:

Whenever you use a full-attack action or flurry of blows to make multiple attacks against a single opponent with unarmed strikes, total the damage from all hits before applying damage reduction. This ability works only with unarmed strikes, no matter what other abilities you might possess.

Now, is Hardness considered a form of Damage Reduction, or is it completely different? If it's different, does Pummeling Style not work with Sundering properly, because you can't add your hits together on the object being sundered? Was the intention of Pummeling Style to work this way?

By the concept, it doesn't really make much sense for it to NOT work with Hardness and sundering. If necessary, I'd like a FAQ reply to this.

Damage reduction and hardness are two very separate things - why would anything that specifies working on one work on the other?

[Kiesman]

My reasoning is because the entire concept of Pummeling Style is that you hit the same thing repeatedly super fast in the same spot, so why wouldn't it be usable (with the same effect) when hitting an object as opposed to a creature?

DR is a construct its nothing tangible and magic enough weapons can overcome a lot of it. Hardness is tangible thing and even a weapon becoming +5 doesn't suddenly start ignoring it.

Hardness and DR are separate things. You also need not visualize that Pummeling Style is striking the same spot repeatedly, but more as the flurry of attacks are so effective as to be like one attack to overcome DR. It has no other effect.

Hardness is the innate strength and quality of a constructed thing, be it wall or magical sword.
