Whoopeeee!, you managed to bypass the system, back in the day..... Lucky you!!! Perhaps times have moved on and DPE's have become more switched on?
I can tell you that today, someone who tries to add an FAA IR to a 61.75 certificate who does not hold a night qualification on the underlying licence will not be able to do an IR until they either gain an NQ on the underlying licence or do a full FAA certificate.
Glad you got through though.
