How did you get Olysio 10,586 TRx? I saw other cited that number as well. For same period Sovaldi with about 57,000 TRx, I can only get slightly over 8,000 TRx for Olysio, about 15% of Sovaldi.
Unfortunately I think that I made a mistake by one week. I still do not get your number, but the number is lowered to 8934 for Oly. The math changes to 354x(57134/8934)x(84000/66000)=$2.88B. I will have to think about changing my number. Probably will not, but shows that there is a reasonable argument for a higher number. Anyone with enough guts to give one over $2.5B?
