I think autostop mostly occurs at or below 19mph in neutral doesn't it? [along with several other factors....with a/c in ECON mode, engine warmed up, etc]
Mine is finicky about autostop and the speed varies, sometimes 19 sometimes 15 sometimes 10...you get the idea...its not an exact thing - I don't want a new owner to think his car is messed up.

Maybe different cars have different "personalities"? Mine shuts the engine off at 22 MPH every time, now that I've had a little practice at it and can time it just right.
During deceleration with foot on the brake, I am in fuel cut. ( 9999 MPG on the SG )
When I see 23 MPH I push in the clutch, and shift to neutral at 22 MPH. Bam. AutoStop every time if things are warm, and no A/C use, etc. I go from 9999 MPG engine on, fuel cut, right to AutoStop. Nice....... "feature"....
If I miss the clutch press by 1 MPH early, gas comes back on, and AS is delayed a few seconds / MPH.
Foot on the brake is key. You must be doing this too.
