PACB added seven PacBio RS II instrument bookings during the quarter
...and ended the quarter with 10 instruments in backlog.
In the 1Q they added 4 instrument bookings and ended 1Q with 6 instruments in backlog.
So they converted 3 instruments to sales in the 2Q, or half of their backlog. If they can covert half of their backlog in the 3Q, that would mean 5 instruments or roughly $10 mil in revenue for the 3Q.
