Suggested Workout "Anearobic" results a little surprising

The daily suggested workout is a great feature which is helping me to work some much-needed variety into my workouts. That's the good part.

The problem is this:

When I run the suggested Anearobic workout, I follow it to the letter, and hit the pace targets very accurately. This is reflected in the charts I get at the end and that's all fine. But it never "credits" me for the anearobic work. It gives me a 3.0 for Are and a 0 and Anaer. Now you might put that down to wrist HR inaccuracy, but when I do the fast parts I do check the HR gauge and it shows me well into the anaerobic range. So the watch is at least showing my HR correctly - at least the gross number that shows up on the screen, and it shows that I'm in the right zone. So, I'm a little puzzled at this.

Meanwhile, I cannot now put my hands on the reference, but seem to recall reading somewhere that the onset of anaerobic training effect isn't based on the HR per se but on the inflection point of HR variability. Is that correct? If that's true, I could see where the strap might help.

Other odd thing is that this suggested workout is not giving me a HR graph. Same watch gives me a graph for other workouts. I'd like to experiment with making the HR visible on the screen (as a number not a gauge) to see if that coaxes the HR data and chart into the output. But I cannot even find that Anearobic suggested run on the connect website. If I could find that I could download it, edit, etc... to give this a try. Appreciate any tips on this as well.

Well, I wouldn't want to call this a "solution" per se, but a work-around emerged. Today when I did the recommended anaerobic workout (same intervals as last time, 8X:40 with 3 minute recovery between, warmup before.cooldown after) but this time I goofed around with the settings and set the "Target Mode" to target HR instead of pace. Lo and behold now I get the HR graph in my results summary.

Not only that, but having done the exact same workout twice, this time it gives me 3.7 for Aerobic and 2.7 for Anaerobic (vs 0 for anaerobic when the targeting was based on pace, the default). now, of course it's true that one never does the same exact workout twice, cannot step in the same stream twice, etc... but I think there is a marked difference in the watch behavior depending upon whether it's set to target HR or Pace (pace is default). It's hard to think that this divergence in behavior resulting from that change in settings is intended. Also difficult to think that the absence of HR plots/data when the default pace targeting is use is intentional.

For myself I simply won't goof around with the default setting any more and will just leave it at HR based targeting, as that has given me all fo the data and feedback I'm looking for.

Hope that's helpful to others facing this issue and maybe serves as a trigger for the FW team to see if this issue can be replicated in simulation so its cause can be tracked down. Probably a very simple thing at bottom.
