Appearances can be deceiving. Test them back to back like I did and you will see:
A. K-4 is identical in performance to G-10 in all respects. It is NOT slower, it does NOT climb less well, I tested them, I know for certain I dont just "feel" it to be so.
B. 190's, other than the drag from the rack of you took a bomb or DT were identical in performance. I tested the 190's last time a change was "felt" and it too proved to be false. I know, I tested them.
This is a good example of why you can not put too much stock in anecdotes from even real Ace pilots accounts unless backed up with test data. Humans, in all of their sensory perception are good at feeling relative changes in state, but not absolute values.
Do this experiment to see what I mean. Fill a glass with tap water, and put your finger in it to feel the temperature. Now run your fingers under the hottest water you can stand for a few seconds, then feel the water in the glass again. It feels colder than the first time. Now put your fingers in ice water for a few seconds and feel the water a third time. This time it feels hot.
The water did not change temperature, only your REALATIVE sense of its temperature changed. The same thing happens with these claims of FM changes, folks "feel" they are changed, yet they are not, only the circumstances of the particular moment are different.
