I've watched one of your videos before and I've noticed that you always go head first into a full blown transmission each time you call approach.
They like it if you just say "XXXXX approach, NXXXXX" and wait for them. Rather than go "XXXXX approach, NXXXX is 1000ft for 3000ft I'd like XXXXXXXXXXXXXXXXXXXXXXXXXXXXX" Give them a chance.
As KJAN is Class C all you need to enter their airspace is to hear your callsign back from them unless they tell you to stay clear of Class C.
If the frequency is busy, I do exactly what you say, call into approach with my tail number and wait for them to call me back, but if the frequency is not busy, why not get everything out in one call?
I talked to the controllers here, and they said it really doesn't matter but it is less back and forth radio traffic to get it out on the initial call up. My instructor always said, use the three WWW's on initial contact.

Yeah, regarding Charlie airspace you hear me say in the beginning, that my tail number was acknowledge but as an after thought, I realized I was beyond the outer ring of charlie so you hear me say "it didn't matter"
Either school works on call up, it's just a matter of common sense that needs to prevail. If it's busy, call in as you suggested, but if the freq is not jamming, do everything in one call is the way I work.
