The charts do vary, I always thought cooked was higher than raw.
I used the Google trick Manny posted recently, just type the food item and the word carbs and the values will come up on the search page. The nice thing is that you have a choice of quantities from a pulldown list. Down the right side of the page is a standard nutrition label with various other values.
In the case of broccoli 148g was 10g carbs(3.8g of fiber) while 1 cup(91g) had the values I quoted, no mention of cooked or raw.
You'd think a carb count would be a constant, akin to the speed of light, but alas this does not appear to be true:)
