Flashing question Kingklip700

[sleeping-wood]

I have to flash a new roof of Kingklip700. The longitudinal flashings are recommended to be minimum overlap of 2/3 of a pan width (from the wall into the pan). This gives coverage of one rib and 2/3 of one pan. Has anyone flashed over 2 ribs or is this overkill? I have tried to show this in the attached photo. Any recommendations?

I flash over the second rib. You can,t have too much protection. It would also allow you to fasten the flashing into the top of the second rib, otherwise you have no way of screwing it down.
