How much of a Free T increase is noticeable?

[UCSMiami]

If the scale is 6.8-21.5 pg/ml scale and a person is 12.7 does one note a considerable difference if increasing 0.05 or 1.0 or ???

In the four free T test done over the past two years I have gone from 12.7 to 9.8 to 11.4 to 12.5 etc. All fasting tests.

Is there an optimal scale based on weight/size/age or other marker?

Pardon if basic questions.

You will not notice an amount like that, but if this is a result of lowering estrogen and lower SHBG, then you may see that a tiny bit. There is not optimal scale, but free test going to be a % relation to total test, so they work hand in hand.
