For the FAA Ir I managed it in 3 weeks with a spare week that I used for lying by the pool afterwards! All the training done on a twin Beech Duchess, exam done on first day, loads of self study in the months before. Give yourself plenty spare time for technical problems and weather.
Average hours for the UK IMC I would have guessed about 18-20?
