Switch Tracking off and apply noise reduction. You will now see what all the "signal evolution Tracking" fuss is about, as StarTools seems to know exactly where the noise exists in your image, snuffing it out.
The reason Wipe backs off is that Wipe (as is the case with most modules in StarTools) refuses to clip your data.
This way, nasty noise surprises when viewing the image at 100% are avoided.
AutoDev will keep solving for a global strecth that best shows the detail in your RoI.
Please note that other parameters such as the 'Threshold', 'Max feature size', 'Filter sensitivity' and 'Exclude color' have no effect in this mode.
You can convert everything you see to a format you find convenient. Give it a try!
