You could always upload a flight log to phantom help, and post results URL here, there may be some indication as to what is causing the drift:-

I looked there already.  They show nothing in the red.  The DJIs I have are perfect.  It must have been the wind though.  I've calibrated all 3 drones today and tried nose down and sideways w/ the Spark but it didn't matter.

Whilst you say there is no wind and even the forecast may also say the same, thats for 10m height btw, once you start climbing, so does the wind speed, so you can add around 10-20mph at 400ft (121m)

I have no idea.  The times when there feels like no wind is happening is when drift occurs easy.  I think when no wind occurs the drones go into some sort of slack mode because it thinks something is wrong.  When wind hits them a lot they are a lot more stable.

99% of the time it will be wind speeds but the need to calibrate the IMU may be on the cards

I have noticed occasional yaw drift with both my P4 and P4A, but have not spend a lot of time researching it or trying to correct it. I have a Mavic Air on order so will see if it happens with this too.

My drone was so stable this afternoon.  I mean rock solid stable!

The Phantom 4 Pro V2.0 is making my clients happy.  Please ensure support updates happen for this drone and the batteries continue being made.  I need for this drone to work flawlessly with the Note 10 as I have the AT&T 12 Next plan and have to upgrade when it comes out.
