Is High Aerobic Shortage bug fixed in 1040 Series software?

I've posted a few other threads in the 1030 and 945 forums documenting an issue with High Aerobic Load not being properly incremented.  This issue is this: unless a ride is labeled “Tempo” or “Threshold” you get ZERO Load added to High Aerobic. Even if the ride has large portions of high aerobic activity. Which is ridiculous because Low Aerobic and Anaerobic will both increment on every ride type.

Does anyone know if this behavior persists in the 1040 and or 955?  Thanks!!!

    I have never seen a short on high aerobic if your training is in that HR zone. Maybe you have some problem with your zones setting. I had one with my low aerobic, but solved changing the zones.

    Hi, and thank you for your reply.

    This issue is not caused by zone setup.  The issue is even though the activity records significant amounts of time in High Aerobic Heart Rate and or Power zones such as Tempo, Threshold, and or VO2Max...ZERO points of load are added to the High Aerobic Load Totals.  High Aerobic Load is only added to the totals if an activity is Labeled as Tempo or Threshold. So a Base Ride with a fair amount of Tempo and Threshold time allotted results in ZERO accumulated High Aerobic Load.  Conversely, Anaerobic Load goes up related to the amount of Anaerobic minutes regardless of the Activity Label.  A ride does not have to be labeled Neuromuscular or Anaerobic to gain Anaerobic load totals.  Only High Aerobic works this way.  Aerobic load also increases no matter the activity label.

    Mountain biking is my sport and its not alway possible to register a 'Tempo' label for a ride even though it can contain TONS of Tempo level effort due to the downhill sections you end up with a lot of lower power and low heart rate minutes.  Which would be fine if the algorithm would just count some of those High Aerobic minutes to the total...but it doesn't.  Anyways.it's been reported that this is a bug and in the past the software worked properly.  I"m hopeful that Garmin will fix it on my devices...but I would be willing to buy a new device if that's the only way to get the fix.

    My sport is also MTB, and I am always on the highest side on anaerobic and high aerobic, my only concern is low aerobic, it was counting almost no time in that zone. But I changed my zones now to use %LTHR and much better now!.

    The issue is not related to improperly set zones.  Even if you spend tons of time in a high aerobic zone the total load will not increase.  Low Aerobic and Anaerobic will increase though.

    You can check out my thead in the 1030 forum.  Basically, unless an activity gets labeled as 'Tempo or Threshold' the High Aerobic will NOT increase.  Even if you spend tons of time in those zones during the workout and can clearly see in the activity data.
