Lonnie... I think I sent too many curves and got us all confused - On the two you sent - The first one was a quick first try and the "straight line curve" did not provide a good "long term" idle.. as it cooled it needed more fuel and to get a reliable idle and acceleration I ended up with the later "big Jet" curve with a pronounced check mark shape - As I went to "small jet" the dip got progressively less and as I closed the HSN to do "your" test it reduced further... I think they responded "typically" as expected and as the dip got less the idle quality improved....

That first Straight line test was misleading as I never spent much time confirming idle... Sorry for the confusion....
