Does anyone use this function on their Polar HRM's.
Ran mine for the first time for a couple of months yesterday and leapt from 44 to 50.
Mind you I'm a bit dubious about the process and doubt person to person comparsions are very accurate, your own trends maybe not too bad.

But honest, this watch was just reading the resting puls. It was about 60. Than it knows my age and weight. With only these information it can not really check my fitnes.
In my opinion this is just a unnessissary information. I know my fitnes, not my watch!
I've only had my Polar a couple of weeks.
1st Own Index was 49 - which for a 42yr old female classes me as an athlete although in reality I'm only moderately fit.
I didn't believe this, so tried again immediately and got 47.
Then 42, and finally 39 (still v. good)!
All except the last one were done sitting at a desk in the evening. The final one was lying in bed first thing in the morning.
Not sure what to conclude from all that!
The result is based upon the variation in heart beats over the elapsed time of the test so is best done when fully realaxed and at the same time each day to be able to get consistent readings. The figures should also be used as a guide to how your fitness is changing as oposed to an absolute value. I say this as by changing my activity level I can change my readings by 8-10 so how can that be compared to someone elses reading unless you are sure that the correct activity level is selected. If your HRM's do not have the ability to set your activity level then the chances are that it will be impossible to compare two persons figures based upon what I have found with changing the activity level on mine. This then meens that it can only be used as a guide to see how your fitness is changing.
My figures that I get do however appear to tie up quite close to the results that I get on a 'bleep' test so I tend to treat them a close to my VO2Max figure.

my intake of caffeine is so massive that there would probably be no point trying it caffeine free....
