HRM

Ok I have a question and I am really hoping someone can answer it. Does your HRM give you are avg.hr, peak hr and calories burned? If so what is your avg hr and what do you normally peak at? Using today my avg hr was 154 (for 60 minutes) peak hr was 190 (which is normally 180 just worked harder today lol). People are telling me that is way to high what do you think??
