Bought the lactate pro 2 meter and used it for 2 threshold sessions. I’m a 15:25 5k runner. I did 6x5 min @3:31 km pace and my lactate meter said I was 23.0mmol/l. I feel likes there’s no way I’m at that lactate when running at a pace like that. Does anyone know how to fix this issue or is it right?
I bought a Lactate Plus meter and did a step test on the treadmill yesterday that left me just as confused. What's worse is that it failed to read the most critical stage around my threshold due to "Not Enough Blood".
My values were:
1.3 mmol/L at baseline.
1.1 mmol/L at 10 km/h
1.4 mmol/L at 12 km/h
2.1 mmol/L at 14.2 km/h
X mmol/L at 14.8 km/h
10.2 mmol/L at 15.4 km/h
13.9 mmol/L at 16 km/h
18.8 mmol/L at 17 km/h
Some samples were taken from the year, some from fingers. All samples were taken by my sister who is an MD.
These values were surprising, as I have run 16:57 in the 5K, 37:01 in the 10K and a 1:24:30 HM. So to have a 10.2 mmol/L reading just above my HM pace is just questionable.
Also, my treadmill is accurate and I gauge this with an NPE Runn Optical Sensor.

I appreciate the science of running as much as anyone, but runners are not lab rats. You are there to run and race, to actually compete at some point.
The measuring gadgets are fine to use to back up what you are feeling in training or help guide the training, but at some point you just need to look at a stop watch and be done with it.

My maximum heart rate is 203 bpm.
Warm up heart rate averaged 130, maxing at 152.
Test avg/max:
First stage (14.2 km/h) = 155/165.
Second stage (14.8 km/h) = 165/171.
Third stage (15.4 km/h) = 163/175.
Fourth stage (16 km/h) = 172/179.
Fifth stage (17 km/h) = 180/187.
These were recorded with a Garmin HRM-Pro Plus chest strap.

I'm not sure what value you bring into the discussion at hand.
Yes, running can be as simple as you want it to be, but there is no harm in using technology to better steer your training and optimize one's energy systems.
Also, not all of us are out there competing and racing high caliber runners. Some of us just value the power of data and that in itself is joyful and motivational.
No need to put others down just because they don't approach the sport the way you do.
23mmol is definitely wrong. You'd be puking your guts up at that level. I had a step test done in a lab and the PhD there told me anything over 18 is puking level for most. Sounds like human error. It takes practice to get an accurate reading, especially by yourself. Might also be a calibration error - there are some calibration fluids you can buy to ensure it's not a machine error. I'd start with practicing the sampling though.

This is the type of info that we’ll help in these studies. My gut tells me accurate HR monitor measurements are sufficient for providing good data in conjunction with ‘paces’ and ‘feel’, and a lactate meter is an overblown gadget for most.

That said, I don’t want to throw water in what you are doing. You are doing a good job in data acquisition, and objectively looking at the data and checking your measurements. Maybe there is more to learn with a lot more participants contributing to the lactate tests.
I do have a (somewhat related question), if you are using the lactate pro 2 meter that is, what does the large number mean? In comparison to the smaller number right below it with the unit being mmol/l.

I've been alternating running by feel and HR for most of my years, but I've started doubting the premise of running by HR during the brutal humid hot summers I experience yearly. Thus, I am trying to answer questions that I could not find answers to in science literature and/or internet forums.
Questions such as: Would running two different paces under the same HR illicit the same lactate reading? (Assuming identical distance, route, gear etc..)
Apart from the obvious quest of finding a more accurate lactate threshold estimate.
You are on to something, for I too face training in brutal hot humid summers. I found under such conditions, when the misery index (sum of dew point and temp in degF) is approaching and even exceeding 165, that I have to slow way down to keep the same HR. By feel is pretty-much out-the-window under those conditions, so I just slog along and kept HR low and in-check.

So that said, being an older guy in my 60’s, under those conditions, lactate is not as interesting or useful, and HR evaluation becomes a health safety check.
