Of course you are right. But everyone who's passed a course will always recommend the way they did it etc..
They may expect more from you, but with 20 hours under your belt that won't be a problem.
Tell me MIKECR, who do you work for now? Where did you have SIM assessments?
I was on a B737 MCC at Oxford when Ryanair showed up for a recruitment day. They looked at me an my mate wierd when we went up to them at the end of the show and said we were only doing the MCC. They actually said to us why are you not doing the JOC, as it will be less of a risk on the type rating with the extra experience from the JOC. God only knows what he would have said to someone who did a MCC on a Kingair.
Needless to say, my mate and I are on the 737 type rating with Ryanair now, having passed the sim check. Not having any problems on the type course so far, touch wood.
