    Honestly, I really don't know. That's why I don't bother with an HRM. Maybe try walking the same distance at the same pace that you walk when you do that - that should give you a pretty accurate accurate reading for walking - and just average what you get between walking and what your HRM tells you from your walk/run combo? It probably won't be quite right, but it should be close enough, I'd think. But that's just a guess.

    A HRM is accurate for intervals, HIIT, steady cardio, and weight lifting. The calculation is based off of your body metrics and heart rate throughout the session. So, at elevated heart rates you burn more calories. When you have large fluctuations in heart rate, say with weight lifting, you will notice you burn very few calories compared to a cardio or HIIT session. An example of HIIT would be a P90X routine. Now, are there more accurate measures, of course. And are there HRM's that are more designed for varied activities (cardio, intervals, lifting, etc)...yes. But a HRM that calculates calories is going to be pretty accurate for what you need.

    If you want, you can do a simple test. Do weight lifting where you do slow reps, take breaks between sets. Another day, do the same workout but have, say, 15-30 second breaks and increase the rep speed slightly. You will see the 2nd workout burns more calories, and you will see you were at a higher average heart rate for that session.
