People usually don't advocate racking until the specific gravity is stable for at least three days.
It looks like the apparent attenuation is around 73.3% and the abv is around 10.5%, but that yeast can go a little higher.
I'd go by the gravity readings and not the numbers. Just my 2 cents.
I really like the 1728 by the way, I used it on a wee heavy and fermented at the very low end of the recommended temperature range. It gave a nice smoke flavor to the brew with out using any peated or smoked malts. It was kind of neat.
