And? Without the weights his base speed is still 4. With them maybe is 3,5 or less.
No. Without the weights his speed is higher than 4, since weightless Lee is NOT base Lee, which is what the databook is based on.
The speed means nothing in Naruto. Raikage is the 2nd fastest Shinobi right now, but Madara ( who is like 100 times slower ) fodderized him.
If you are smarter then your opponent you can make a strategy to take him/ her down.
Madara didn't beat him because of smarts, he beat him because of raw power ( Susanoo ).
Tenten is not alone. Sakura and the others can distract him.
How? Hinata and Ino are useless. Ino's only jutsu will not hit Lee unless he has both of his legs broken. Even then, I am fairly sure he could walk on his hands and still avoid it.
The girls of KN11 are fodders. Deal with it.
And no, lee < tsunade but Gai definitely beats Tsunade.
