Maybe this is from a past experience so far and not from the hair tests considered from the people in this forum.

'Group' 1 and 2 look like are in slow oxidation, 'group' 3 and 5 look like are in fast oxidation and 'group' 4 and 6 look like are in 'mixed' oxidation.
From the ARL, TEI tests for those who look like Slow oxidizers there is only one test so far that show 1 heavy metal in high range, the rest hair tests show mid acceptable range or none excreting at all.
From the hair tests that look like from a fast oxidizers there is also only 1 test that shows heavy metal into high, the other test with very high metals is from someone not on the forum, even though his levels are very high. The rest of hair tests have very little in acceptable range or none at all heavy metals excreted.
From the hair tests that look like are in 'Mixed oxidation' there is also only one test that shows a heavy metal in the high range, the rest hair tests are either mid-low normal range or none excreting at all.
Hair test is probably not the best for accessing heavy metals in general, but after certain provocation might show excretion of heavy metals.
Just looking at those around 40 hair tests its not so clear which oxidation type have the most heavy metals in general, but its interesting why the one who are in fast oxidation are not presenting way more heavy metals if their detox pathways are open wider compared to one that are in slow oxidation for ex.
On other hand the one in slow oxidation or fast or mixed with none excreting any heavy metals, is that means there are no heavy metals in the body, but just the body is not getting rid of them at that particular time.
