That still requires perfect timing. Getting the timing right on a long-term contract is even harder than with a short-term contract!
The point of LEAPS is you don’t have to perfect the timing. You buy far enough out to avoid theta decay, and far enough out of the money to minimize risk.
How does buying long term put options require perfect timing? The whole point of a long term put option is that you only have to be right at some point between when you buy it and when it expires.
