Well done, Lunin.
Imma take my stab at the practicality debate, though, in saying this:
Reading, thinking in words, and thinking are three different creatures. To use this isn't to preach it in your head before battle, but to not get caught in the "melee haze." That fog over thinking when you're playing. It's a matter of paying attention. Most people run through a mental gauntlet of specific move combos that are almost preordained... and that's where the thinking part comes in. Aiming for your opponent with a f-smash instead of Shufflin a nair and wavedashing back to.. do something else flashy and gay.
A good 50% of this happens subconciously simply because of operant conditioning (Did I take my first college psych classes or what! Woooooo!). Pidegons pressing the red button for feed, kids over using Marth's F-smash. Pidgeons not pressing the green button because of the shock, kids not using the F-smash anymore because it gets Shield-grabbed. It just depends on how dense you are.. if you're the ********, emaciated pidgeon or the the well fed one.
Not to put words in his mouth, but as a means of clearification, I think Lunin isn't preaching you sit there and "Hmmm... Why?" during the match. That's inpractical. More so, to keep a light bulb, even if dimly lit, so that you're not another starving pidgeon.
