Many things can alter this from a slight chest infection to the time of day. It can jump either way.
Hi - yes it can fluctuate, cold morning on a full English breakfast will get you a significantly different result than a warm summer afternoon on empty, for example, and there are other varying influences in my experience. Also you will see a change after the tail off from Preds - they usually avoid spiro within 6 weeks to dodge the influence.
I'm not sure that your age matters that much in this ratio - believe 80% Fev1/FVC means you can blow out 80% of the air in your lungs in 1 second - so is in near the top of the normal range at all adult ages.
