Accuracy is relative. As NWMushroom alluded to, potential ppg of a grain is going to vary with maltster, harvest date, harvest year, lot-to-lot variation, sampling variation, etc., etc.
The BYO is similarly inaccurate/accurate to the HBT wiki, the How To Brew table, etc.
The reality is that regardless of the table you go with, they are all reasonably close approximations to the actual value, and good enough for our purposes.
