Hey, mrrumba, let me add my welcome. I was really lucky, I guess, that when I started learning to dance I was taught "single rhythm" for East Coast Swing. That would be simply step, step, rock step. The step, step is "single rhythm". The rock step woudl be a "double rhythm". There was also a "double rhythm" swing, which is step tap step tap rock step. The version you were taught uses a "triple rhythm", then the double rhythm for the rock step. Guess which of these is most difficult? Based on the wrtings of Laure Haile, who was a national director of dance for Arthur Murray studios, you were supposed to know all of these rhythms to dance "swing" and advance to "Western Swing", which used all three rhythms and considered to be "what to do after Lindy". Also, in the early 60s, at least one writer noted that you could/should use the less demanding double or single rhythms for faster songs. You should note that probably less than 10% of the general dancing population actually dances in time to the music, based on my observations. So, in one sense, you are setting yourself a fairly difficult, but very worthwhile goal. I've been known to compliment total strangers who dance simply, but in time to the music. And that business about losing the beat when leading turns, etc? Happens all the time. If you are AWARE of the beat, and feel that you are off, you are on the right path! (Man, does that bring back memories!) If you stay engaged here, we can point you to a bunch of information that could be very helpful (although it may make your head hurt).
