Default Raspberries affecting ABV

Hey all,

I just brewed my wit this morning, and in a week or so I'll be racking it onto a few pounds of raspberries in the secondary. I think I understand the basic procedure of pasteuring by heating the raspberries in water to ~170 for ten minutes or so, and getting them into the fermenter, etc. What I'm curious about is if there is a way to determine how much alcohol the fermentation of raspberries will add to the beer. Is there some basic conversion formula, or is it entirely neglegible, or what?

Raspberries are relatively low in sugar, as low as 5% by weight. A couple pounds wouldn't add much.

Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"

When I did my holiday porter I added 2lbs of raspberries to the secondary and racked on top, didn't change my ABV in the slightest.
And now we go AG!

My raspberry ale, I don't recall any activity at all in the secondary. I would expect this means that fermentation is minimal.
