Of course we don't know the stepping of the 2G chip, but as Dave said the 2.5G look to be a B2 stepping according to cpu-z. Looks pretty good to me.
The 2.0G was B1 stepping.

Now if there is no difference in the steppings, then yes. Perhaps 15% is a conservative estimate but 20% on average would be max.

It looks like 15% is going to hold true.
