I'm not gonna go over everything, but theres things you say here and there that arent accurate to the current understanding of falco and how he is performing.
Arguably, falco is not fast. Some of his moves might be, but his jumpsquat, horizontal mobility, running speed and weak dashdance make him pretty slow/not mobile compared to the rest of the top characters. He gets by this because of his laser control compensates to some extent. He has many subtle weaknesses other than recovery nowadays including his speed and good sdi kinda limiting his combo game, as well as a bit of struggle against floatier characters. "he makes an effective counter for those tough Peaches." The current metagame does not reflect this, as top falco players are seen struggling against this character relatively. It is very controversial who has the advantage in this matchup, so calling him a counter is not very accurate. Falco is also not unstoppable on final destination. Marth has an advantage here against him, and very good foxes with accurate powershielding, chaingrabbing, and SDI games definitely contest falco here (maybe even very slight advantage). What stage he is good on really depends on the matchup rather than the stage itself (pretty much for all characters, really). Under the pro section: His grab game isn't really a pro compared to other top tiers. he can get grabs, but not really do as much out of them. falco's recovery is definitely not the worst in the game hands down, especially at short range. You again mention fast foot speed and overall speed being a pro which isnt really true. I dont believe falco has any infinites either.
Theres a lot of errors, and I will not go through and address all of them. Its just that some things you say are just so glaringly shocking, that it doesn't seem like you have the best grasp of falco as of right now due to maybe a bit of a lack of experience. Btw, I am definitely not going to claim that I am qualified to write such a guide or that I am even a good falco either for that matter.
