Yes, so maybe I’ll add a couple of comments, Ann, and thank you for the question - this is Sam. Versus what we shared back when we talked about in Q3 of 2022 around the fact that we were somewhere in that 850 range, obviously some positives that you mentioned, which is I think what you are referring to as the $115 million to $125 million, which includes the PAMA delay, which includes also the reimbursement of the specimen collection fees, which we now benefit from. But there are a couple of things also that have changed to the negative, really the key one being--or just one thing, really, that’s changed to the negative, I should say, which is COVID. The COVID assumptions that we had back then were, as Jim just said, 10,000 to 15,000 a day. Now we’re seeing volumes, as we mentioned on the prepared remarks, 17,000 a day in January, and January is typically around the peak of the respiratory season and then it starts to come down from there, so our expectations of 10,000 to 15,000 a day for the year are, I would say, realistic. But in terms of the range itself and what differentiates the bottom versus the top, I think it’s going to be really around the COVID assumptions. But again, keep in mind we’ve taken COVID down by $150 million in terms of total revenues versus what we really shared back in October, when we expected 10,000 to 15,000. We’ve also--from the benefit itself, you know, the $115 million to $125 million that you referenced, we’ve also carved out a small amount for investments in the business, strategic investments that, as we said a couple of months ago, we said we will reserve some of that benefit to invest in the business for long term growth.
