The numbers are a guide only. What is more important is the long term trend, particularly if you are training specifically to affect aerobic capacity, aerobic or anaerobic threshold, lactate threshold. Get a measurement at the start of the specific program. Get a measure at the end. Has it moved in the right direction? If not why not?
