You're most welcome. I'm just glad to see the data, I was looking for this a few months ago when I first got my Polar and wanted to know how accurate this is. All I ran across was a bunch of men saying the OwnCal data was accurate.

Yeah, it's accurate... for THEM!

What really scares me is that the article made complete and total sense to me. I've had to do a lot of scientific reading of this nature lately what with going back to school this year. A year ago I would have had a very hard time reading that article, my eyes would have been crossing. Help! I'm turning to the dark side of academia...
