Terrain Scullping Tool Values

Can anyone explain what the ‘tool strenght’ value actually relates to? Given a terrain, can one predict how much in % or units each mouse click will raise / lower the terrain? And, what does the ‘target value’ mean?

@anonymous_user_8932ba9e High tool strength means the landscape will react much more quickly to mouse clicks, target value combines this with a max value.

Is there anyway to quantitatively how much each click will raise the terrain?
