Honey Rye Double IPA

My own recipe based on what I had in inventory. I am going with a single hop and chose Chinook for its pine resin, spice and grapefruit notes. I thought those would pair well with the spice of the rye rather than using a fruit based hop that would probably get drowned out from the rye. According to a chart on Brewer’s Friend, a Rye IPA should be 50 to 75 IBU and a Double IPA should be 60 to 120. I adjusted the hops in the recipe and am going with a projected IPA of 80.5. I did see when I switched from American Pilsner Malt to Wyermann Pilsner malt the IBU went up to 81.11, but after multiple saves, it is back down to 80.5. I manually changed water requirements as max that I can use in my equipment is 22 liters on a sparge or grain won't fit. 22 liters strike and 9.15 sparge. Changing back to US units will change L to Qt but not change the quantity. It also changes the hops from grams back to ounces and fermentables from KG to pounds but those quantities change as well. I accidentally added the hops at 50 minutes rather than whirlpool so the IBU went up a bit.
