Second series 2619, 2624, 2666 and 2650.
Last three were 2656, 2666 and 2704.

....This was over about an hour or so. The light conditions and temperature were changing which might explain the velocities that kept rising?....

Velocity will generally increase as a new barrel breaks in, although that is quite an increase. Some chronographs will give different readings dependant on the light conditions.
