Yes Keygrip thanks I remember that point now (I stand corrected!)
Just to be very sure that you won't have any problems, and to keep things simple, I would recommend just getting the night stuff done in the first place.
I BELIEVE that regarding the IR before CPL, you should have night done before commencing training, but as Keygrip alludes, there is small print in LASORs.
I say again: just do it and get it out of the way (before the daylight starts getting a bit late again) and therefore be sure you will have no problems!
