I find the same with DIY Dog recipes, they get much better hop utilisation than homebrewers get. I'd personally increase the amount of hop to what you need to hit the target IBU.

You will get ibu' s from the other additions but your software isn't counting them

If your adding the "steep" hops straight after flame out that will up the ibu's considerably

Apparently below 80°c doesn't increase ibu's. But I recently did a NEIPA with no additions until steep and that still came out quite bitter.
I would just follow the recipe you have and if your not happy adjust it next time.

You'd also get a more IBU points from a 90 min boil, with the bittering additon at 90 mins too. A lot of commercial brews boil for 90 mins (I dont know if BD do though). DIY dog normally says 'start' in the reciepes doesnt it? So you have no idea if they mean 90 or 60 (or even something else)

They do, but they also state the boil time for the particular beer. So the start addition is the only one we can be certain of with BrewDog.

With this Beavertown recipe, I'd say it looks spot on.
