hardrock is *1.4
caps at 10
You can see this by putting hardrock on an AR7 map and comparing the speed to an AR10 map (without hardrock). You'll see they are almost the same, but the hardrock will be slightly slower.
7 * 1.4 = 9.8
You can compare by editing a map to AR7 and flipping a map for hardrock, then unflipping it and setting AR10. Take screenshots at the exact same time location and directly compare them. The closer the approach circle is for the next few notes, the slower the approach rate is. Alternatively, you can just believe me, and I can provide screenshots if you really want.
You can also edit circle sizes in the same manner; you will notice that circle size 4 + HR is a bit smaller than circle size 5.
@Shiirn: It doesn't round down, at least not for standard mode. AR7 + HR is definitely faster than AR9.

Circle 5 (flipped the notes) http://puu.sh/36Hi
Compare them and you can see Circle 4 + HR is slightly smaller.
