Amsterdam ‘Wet Hop” Beer

Something is not right with the IBUs, I've added the ingredients incorrectly - IBUs are about 10x expected. If I divide all the hop quantities by 10 then things look good...help would be appreciated.

***assuming hops are 80% water, quantities below should be reduced by 80%.
