Well that's major balls. Shooting multiple approaches, go arounds, engine failures, all in night IMC every 6 months for 4 hours (not to mention operating on a daily basis under IFR) isn't enough to let one fly a 110kt putput single engine machine IFR?
That 1 hour every 6 months isn't for single engine ops, but single pilot ops. So in the above case, you are allowed to fly that 110kt single IFR. But, a pilot who flies with a co-pilot (and thus might share IFR duties) cannot go alone without that recency.
