It's because i am trying to learn how to use a heart rate monitor . Some of you are being very helpful so thankyou
Your arrogance is astonishing. You say you are trying to learn, but you won't listen to those trying to help you.
I was the first to respond to this thread (second post, page 1) where I asked you to clarify what your numbers were - all I got in return was a series of smug, arrogant dismissals and then you apparently put me on ignore. I would urge anyone reading this thread to re-read the first couple of pages again, just to remind themselves how utterly stupid that was. Simply stating 'zone 2' or 'zone 4' means nothing as there are an infinite number of training zones out there, depending on how you define them. One rider's 'zone 2' could be entierly different to another's, as this thread underlines.
Over the length of a 2-3hr ride, hitting an average HR is fine because staying in a single zone over that length of time will be practically impossible, unless you are on a long, flat, straight road with no junctions that you can ride for the duration.
The biggest issue is that you genuinely don't seem to understand WHY you are doing it. What was the expected training benefit from your last ride in zone 3/4/whatever? Unless you are going out with a purpose and an objective, then you don't need HR.
