Right but the difference is Diavolo would know exactly where Pucci will be and how he is likely to dodge. Epitaph would show exactly what Pucci would do, how he would react, and where he would dodge.

Combining that with King Crimson's ability, Diavolo would know exactly when to strike and when to skip time. It's not like Pucci could suddenly change his mind, since Epitaph's predictions are absolute for everyone except Diavolo.

The only reason Jotaro failed was because of timing. As fast as Star Platinum is, it can't keep up with Made in Heaven. But Diavolo doesn't have that problem, because he can make himself immune to Made in Heaven's attacks with King Crimson and would know exactly what the timing is to hit Pucci because of Epitaph.
