target IBU = 45

The only other information I have is a 33% utilisation of the alpha from the start of the boil, about 15% 10 mins from end, and about 5% when added at the end of the boil. Is this sufficient?

I have been sent a recipe that gives hop additions as: Chinook: about 30% of the alpha, add at start of boil Chinook: about 20% of alpha, add 10mins before end of boil Cascade: about 20% of alpha, at the end of boil Citra: about 30% of the alpha, at the end of boil How can I convert these...
