Independent research by Dr. Bryan Heit contradicts some of the manufacturer's information regarding re-pitching. Dr. Heit's data suggest that as long as Philly Sour is re-pitched quickly (the death rate was ~1%/day), it can be re-pitched up to at least 10 generations, and probably re-pitched indefinitely if the correct cell count is pitched. Cell counts should be performed in order to verify that the correct pitching rate of ~0.5-1 million/ml (use this same pitching rate for different gravities of wort) is maintained since pitching under or over this amount produces less pH drop. This culture works better when the wort is well oxygenated and highly fermentable.
