Sounds fairly standard then.
Take a well-known and easily understood product and 'improve' it out of all recognition.
HTF can you take a measurement throughout the last 400 yards? Do you have someone hanging on your wrist measuring your pulse? Do they multiple the time for the last 400 yards and multiply it by 4.4?
If you are going more slowly in that last quarter but you have a high
PR then your readings will be low - fail. If OTOH you speed walk that last section your
PR will be high but your time short. Which will be better?
I just span my figures, cutting the time by one minute and upping my heart rate by 15% returns the same VO. Cutting the time but for a lower
PR increase gives an improved VO compared with the full mile. So, start slow, keep your
PR down then leg it over the last 400. Job done.
