i don't think that's what was meant, rather...
- select the images that form one row, and spread them horizontally using "fill yaw" in the "image parameters" tab, as closely to the actual shooting pattern as reasonably possible.
- set approximate pitch for that row, using the grid (there's no rectangular interface for this, unfortunately).
until all rows done.

it shouldn't matter much, as long as the control points (cps) are accurately positioned, and cover the whole image overlap. for this purpose, it is best not to rely on the automatic cp generator, but to add the cps by hand.
that said, since you have 300+ images i suppose you're not using an extreme wide angle. i'm not sure that having good lens settings is really critical for cp generation in this case. 3 images are not enough to get a good fov, anyway...
