Not really because you don't know what nature that spread comes with, and it's more than likely one you won't want. There's a couple of links on the first page that have some good spreads that you can use.
EDIT: Nevermind, the spreads you can use can be found in the first post at the very bottom of the How to Capture Perfect Pokemon guide. You can also use Wichu's PokeRNG too.
