Frank that might not be as far fetched as you think. The A330 and A340 were not common type ratings either. Over the years many people lost either their A330 or A340 recency and took next to nothing to get current again. Most of the times I did it it was 3 landings in the sim with a sim instructor, could be done in 30 minutes without a training captain.
