***", you do not have enough runs entered to make a prediction. If the prediction is
displayed as "EZ= N/A", the prediction is for a plate larger than the largest possible
plate, or smaller than the smallest possible plate.
NOTE: Barometric Pressure
The Pressure reading is "Absolute", which means it will NOT agree with the
weather channel or local forecast. This is due to the fact that the local forecast
is gives a corrected pressure reading that is compensated back down to sea
level. If you were to stand at your local airport and dig a hole down to sea level
the PerformBJSF pressure reading would then agree with the local airport
reading!
