Oh, indeed. Well, the phrasing still easily leads to confusion as it could be interpreted as falling to $22 million (which is way too little), rather than falling by a range of $17-22 million.
Would've been better as "revenue to nosedive by between $17 million and $22 million in the quarter"
That number can't be right, though. They have a billion in revenue per month. You wouldn't describe a 1% decline as plummeting.
