I've just seen that Butterfly have changed their rubber rating values.

According to their website, Dignics 09C has a spin rating of 96, and the only other rubber that has the same rating is Tenergy 05 Hard.

I've heard a handful of very high level players say they think T05H still has the highest overall power (i.e. spin + speed) potential of all Butterfly rubbers—it's just more difficult to control compared to the Dignics series. Interesting that Butterfly's own testing, whatever that is, seems to support that.

The spin rating refers to the amount of topspin you get from a loop. However the amount of spin you actually get depends a lot on technique. No doubt Butterfly's ratings are based on the amount of spin that a professional gets on their loops, which will be quite different to the amount of spin that most of us get.

T05 Hard requires good technique to get maximum spin, mainly due to the hard sponge. Most of us will likely get more spin from T05 or even T05FX because it's much easier to get high spin with these rubbers, and more forgiving of poor technique.

Dignics 09C requires different technique to get maximum spin because of the tacky surface, which again requires the right technique to get maximum spin. Those of us that are used to tacky rubbers (like many Chinese rubbers) will probably get more spin out of 09C compared to T05 or T05H because our technique is more suited to those rubbers.

I find the more tacky a rubber is the easier it is tog spin with a brush stroke.
The less tacky a rubber is the more a full contact stroke is required to get hard spin.
This is probably why DHS decreased the H3 tackiness. They actually improved speed an spin for
full contact strokes...

Butterfly rubbers are tested by the pros that use them and are sponsored by Butterfly so it stands to reason that this would match up, would actually be crazy if it didn't!
If there's one company that knows it rubber it is Butterfly, they make them in house in Japan, QC to their own standards and have developed some rubbers specifically for and with professional players.

I'd say that a big portion of this is marketing. Numbers fit Butterfly's strategy. They have changed over the years...

Prior to the year 1980, ®Butterfly Tamasu had always been using ASKER -C scale for their factory tests on rubber products. They changed to Shore-A since then.

Very unlikely to be Shore A. Folks can't just take at face value the stated hardness values and "reverse-engineer" the hardness scale by eyeballing which one they fit in.
