WhiteBerry CFL Harvest (Top Half)

Here's my 1st successful harvest. I just cut down the main cola's and complete buds, about the top half of 2 plants.
In the pic with all my trimmed buds, the largest on the far left was almost 50grams wet. Does any1 have a guess on what my yield will be?

Nice crop man. Rule of thumb on grow harvest is the bud will loose 60 to 75 percent of its own weight when dry. My math says 12.50grms on the one bud but my gut says 14 or 15grms.
