Multi - I can lend you a book on how to use your HRM if you like, which explains all those terms and more - it's quite useful, if a bit techy for me. I had to get Mr Snail to read it, set my HRM for me and then tell me what to do, but that's because I find all of that stuff really boring. He, on the other hand, found it fascinating, but then, he did buy it for me for Xmas, along with my Garmin Forerunner. Blokes and gadgets, eh?
Email me if you want to read it and I'll bring it along tomorrow night. If you ever turn up... ;-)
