Are VW Bugs mystical magical?

OK, I keep my VW bug sort of hanging around but I don't use it very often.  In fact, from looking at my records, I haven't driven my VW for a whole year.  But it is still there in the driveway.  Its got gas in the gas tank. It has oil in the crankcase.  Its got spark plugs and everything it needs to run.  But now the time to get it inspected is coming up, So I need to make sure everything is working correctly.  So I go to start it.  I keep my battery outside of the vehicle and I keep it charged using this charger/maintainer I bought a few years ago, because I learned my lesson a long time ago that if you leave the battery in the vehicle for very long it will just run down and loose its charge.  So I put this charged up battery in the place where it goes, I hook it up to the ground strap and the other big wire.  When I turn the key to ON position, the red and green lights come on nice and bright.  I turn the key to start and I get Rrrrrr Rrrrrr Rrrrrrr Rrrrrrr.  The engine turns over again and again, vigorously since the battery is all nice and charged up.  But it won't start.  I start pumping the accelerator because this always seems to be necessary to get it to start.  Pump, pump, pump, Rrrrrr, Rrrrrr, Rrrrrrrrr.  It won't start.  Now when I get to this point in trying to start my car, I think, ok, its getting gas (I actually remove the air filter on top of the carburetor and visually sight the jet of gas being emitted as I pull the throttle lever back and forth) but its still not starting.  So it must be that there are no sparks being generated.  So in order to see if this is true, I then employ a technique I developed many years ago that every VW bug owner should really know.  But in case you don't, here it is:   I want to see if I get sparks, and if the car is running, you can do this by pulling one of the spark plug wires off of the distributor a little bit, not so far away that it can no longer jump the gap. Then you can see if there is a spark getting through.  But if your VW bug is not running, well, you want to do the equivalent of turning the ignition key to get it to go Rrrrr Rrrrr Rrrrr while you are sitting back there with the distributor.  What I do is, I take my jumper cables, I hook one clamp to where my positive wire from the battery connects into this starter-relay thing I got installed long ago to help me start the car.  And then I hook the other clamp to the side of this relay.  Once I've done that, I can activate the starter just by bringing the 2 jumper cable clamps on the other end together.  So while I have the engine turning over (Rrrrrr, Rrrrr, Rrrrrr), I pull out one of the spark plug wires from the distributor a little bit.  And I see there are no sparks.  But then I remember that I actually need to have the ignition key in the ON position when I do this, so I do that and try again.  I see sporadic and seemingly weak sparks every now and then.  So I am thinking, gee, what do I do?  Do I need a new coil?  Should I replace all the spark plugs?  Is voltage getting to the coil (I check using my VOM and it is getting a little over 5 volts).  Do I need to make sure the whole circuit that the electricity has to take to get from the positive terminal of my battery to the coil is ok (at this point I am always surprised to see what a skinny little wire is carrying the voltage to the coil)?  Like make sure all the connectors are shiny?  I keep pressing together the 2 clamps, and get Rrrrr, Rrrrrrr, Rrrrrr.  This has all gone on for about a half an hour.  Now, just for the hell of it, I pump on the throttle lever to squirt some gas into the carburetor, and the engine starts.  Wow, I got it!! It starts to slow down, but I keep it going by increasing the RPMs if it starts to stall.  Pretty soon, it is happily running.  It is running fine.  Finally, I decide to drive it around.  It runs great!!  I drive it around the neighborhood for about 3 miles.  Then I come back and park it back in the driveway where it has sat all year.  While it is still running, I pull off each spark plug wire from the distributor, one by one, to see the sparks.  They all look like nice healthy, blue sparks.  I finally turn off the engine.  I wait a few minutes.  Then I try to start it again.  Rrrrrr, Rrrrr, Rrrrrr .... sigh ...  it doesn't start.  But the battery is pretty weak at this point.  But I have had my fun and call it a day.  I bring the battery out and hook it back up to the charger/maintainer.  It has to charge for over 30 hours before it is back to full charge!  Ok, so 2 days later, I install my charged up 6V battery into my VW Bug again.  I sit in the drivers seat, I turn the ignition key, and, bam! it starts up IMMEDIATELY!  Notice that nothing is different than what I did 2 days ago, at least as far as, I didn't replace any parts or anything.  Its like, if you don't use this machine for a long time, it kind of forgets what to do, and you have to coax it into remembering what it was like to run.  But once it remembers, then, voilà, it has no problems.  It makes no sense to me in a physical/mechanical sense.  But maybe one of you VW Bug experts can explain it.
