how to calculate stops (see my math)?

I have found the VR to be very effective with the 10-30mm and especially the 10-100 powerzoom.
one shot:
100mm at 1/4 sec - iso800, f5.6. Perfectly sharp. Quite surprised by this.
If it is using the 100mm, this would be 1/100 --> 1/4 = 4 to 5 stops!!
and if that 100mm is translated to the 270mm equiv, then ~ 6.5 stops!!!
BTW, which calculation is correct (100mm or the 270mm equiv?)
Another shot, that I was quite surprised by, was:
30mm at 1/6 second (81mm equiv). The numbers are not as impressive as above, but I was shocked at how good it looked, iso3200, at night.
