Hop Extract

[Cajunbubba]

Yakima Valley says 1ml of hop extract in a 5 gallon batch of 1.050 wort for 60 minutes will produce 10 IBU’s. When I input that into Brewers friend Recipe builder I get nowhere near that.

I don't use hop extract, but what do you put in for the AAUs/IBUs in the recipe builder for the addition?
