One more question

Sorry to dredge this up from page four, at least it's not four years old.....

So in light of the computer keeping track of starts and stops and how long and hard and fast you drive, if you have to access car electronics, i.e. for me retracting my top, is it better to start the engine and do it via the center console buttons or do it via the metal key in the drivers door (manual) system? I am not going to alter my routine of cleaning and lubricating my top seals on a somewhat weekly basis, but I can't imagine that doing this simple thing is causing a huge drain on my battery. It's counter-intuitive, but it seems like starting the car and using the power generated from the engine upsets the computer more than using a draw off the battery. All in all both scenarios seem to be "negative" imputs to the computer. Which is the more detrimental?
If your sport doesn't put blood, dirt or grease under your fingernails,
then it's just a game.
