Using styles - how to set "strength"

If I want to save “contrast equalizer” “clarity” with strength 0.4 as part of a style, how do I do this?
When I create a style from a picture it only seems to save “contrast equalizer” with no preset applied and strength 1.00

the strength of 0.4 becomes new 1.0. If you see the points on the chart, they will correspond to what you would have at 0.4 in the original settings. Its just re-scaling it.

Great - many thanks. What was confusing me was that reapplying “clarity” had an effect on the picture. Presumably this was just applying the “clarity” transform on top of the existing “clarity” setting, doubling or squaring the effect.
