Suggestions on workout changes based on FitBit Charge HR data? (cross-post from FitBit group)

Looking at data from my FitBit Charge HR from doing ZenLabs 10K Week 1 Day 3 workout (W@3.5,J@5.5mph)

My max HR was 153 bpm about halfway through the workout and you can see where, between 25 and 30 min, I increased my walk speed from 2.5 mph to 3.0 as I intend to keep walking past the end of the workout (while I finished watching the show on my laptop).

Wasn't sure how to interpret the data so looked up a HR zone calculator on http://www.digifit.com/heartratezones/training-zones.asp and entered my age, max heart rate (220 - age) and resting HR (calcualted by my FitBit) and produced this chart of zones.

Still not sure how to interpret my data, but guessing I don't need to increase my jog speed just yet as 153 is between Zone 4 or 5, depending on who's limits you prefer, but I may want to increase my walk speed i.e. while my average HR is 126 bpm for the entire workout, my HR during the walking intervals dropped below 120, dropping me out of zone 3 (Stamina) and into Zone 2 (Endurance) and the FitBit chart shows my HR occasionally dropping out of the cardio zone into fat burning.

Any thoughts?
