I'm guessing that you shouldn't really get any misfires, but I've done some logging recently and have found that I get the occasional misfire on cylinders 1-3, never when the car is under heavy load, but sometimes immediately after a WOT run, or when cruising to a stop, idling etc.
When I say very occasional, I mean on a 15 min run which included warming up from cold and 2 WOT runs, had about 10-20 secs on each of cylinders 1-3 at different times registering in the misfire count. They only did it each once (although cylinder 2 read 1 for about 10 secs and then 2 for about 10 secs).
