Reported lactate threshold not making sense

Watch (FW: 12.23) reports lactate threshold as 4:29/km @ 162 bpm but I just ran 4:14/km @ 164 bpm for 90mins. Typically lactate threshold is what one can maintain for up to an hour so it should be much faster than the reported 4:29/km.

My understanding wrong or there is a bug with the LT calculations?

Were you using a garmin chest HR strap? Did you enable auto update option for LTHR?

Yes, the HRM pro strap and auto update

Did a full reset, waited a week for stats to build up and then it started reporting a LT of 4:07/km @ 163 bpm. Something is certainly amiss with the algorithm

They are just estimates. To me the numbers look quite reasonably close.

It is not like 4 compared to 6 min/kim or 163 compared to 190 bpm.

You want more accuracy, then go to the lab.
