Apparent vs real attenuation

When yeast manufacturers list min and max attenuation for a strain are those real or apparent attenuation numbers?

Probably apparent, but it doesn’t matter. Those numbers are for comparing one yeast sain to another using a standardized wort and don’t necessarily have any bearing on the attenuationyou can expect. The composition of your wort determines that.
