Guess-timating Calorie Burn

I use a Timex HRM (chest strap monitor and wrist watch reader) when I work out. The readings never line up with the MFP workout numbers. I'm always afraid that I will OVER estimate my calorie burn so I take the two readings and average it out, or take the lower number. Is this okay?

For my log in numbers I always over estimate food calories and under estimate exercise. Not by much, say 100-200 cals. Is this okay?
