In that case, you'll get 35% for the L segments and 75% for the V segments.

Booking on another website doesn't necessary mean that you will be getting 75%, it all depends on what class you are booked in. Most of the booking engines on the web will offer you the lowest fare which mean it's booked in L, Q or N so you will get 35%. If the difference in Q miles is significant to you, then you should probably book directly with AC or inquire about the booking class before you proceed with the booking.
