Mapmywalk vs Vivofit adjustments?

srecupid

I just did a walk with a very cheap ebay HRM that someone sent me instead of just the strap. I used mapmywalk which uses gps to well map your walk and other factors. I'm curious if these stats seem reasonable for a 172 pound man at 5"10?
Also has anyone paired mapmywalk with MFP and how does it work in comparison to adjustments from a fitness tracker? I know that a fitness tracker compares information between apps but, does mapmywalk do similar adjustments? Or does it just tack on the calories as separate workouts?
