That's for sure - what you cook on it, especially early on, makes a big difference with how the seasoning develops. Fry stuff, etc.
Regarding the OP's cleaning method, I don't think there's anything wrong with that, but it's not really necessary to go that far every time either, IMO.
Just get a plastic scraper like the one lodge sells or similar items on amazon. Personally I use a wok whisk (a traditional tool used to clean seasoned carbon steel woks) made of a bundle of bamboo strips. Use the scraper to remove any debris under a little hot water, dry with a paper towel, put it on the stove over LOW heat for a minute or two, then give the cooking surface a thin layer of oil, wiping off excess.
The heating-water-in-it is a technique I've heard suggested to loosen tough "stuck-ons" that a scraper won't remove. It shouldn't hurt anything but it may or may not contribute to how quickly the seasoning is building, if done every time. Either way, it sounds like more work than it has to be.
