I was just checking out the Garmin 500 data from this morning's ride in Ascent and was surprised to see that it calculated my max power at 882 watts.

This is not a powertap etc, it is a calculated power based on all the known variables that the Garmin collects and that I have entered (weight etc).

Since this is a truly epic amount of power, I just had to know where I did this. Was it that attack on the short hill, or was it the acceleration to catch the little guy who put on a push?

After a quick search of the data I found a short acceleration up a 20 deg hill. Hmmmm. There are some 10, 11 and 12 deg climbs here, but I'm pretty sure I haven't gone up anything this big. Let's double check on the map...nope, nothing close there.

So - I am reminded of the board game 'Monopoly' where you can get a Chance or Community Chest card stating "bank error in your favour" etc. Today I had a data error in my favour!

I think the unit got a bit 'lost' when it was turned back on after a drinks break and didn't calibrate fully before we rolled. When it did gather its thoughts there must have been a wild alteration in the elevation - and the consequent calculation of power was just a little off!

Maybe I need to save up for a 'real' power meter...
