If it were a cloudy day, you will want to push process the film by about 10%. This will boost the highlights and give a stronger gradation If it were a sunny day, the processing time was probably not enough causing a "pulled effect" there by having the highlights mushy causing the lower contrast. When film is processed, the shadows develop to a point and then the highlights keep being processed until the stop bath. With this in mind, a push on a cloudy day will give a punchier negative but a push on a sunny day can render your highlights bullet proof and unprintable. Hope this helps.
