do you have any limitations on what this value could be?
Are there any values that would break the formula if set as curveMultiplier?
If you have limits for this value, it would be good to add checks here that will revert if incorrect value is set.

[MichaelKorchagin]

• curveMultiplier = 1.000 - default. Makes a canonical hyperbola (regular).
• It can be "0", which makes all domain prices max.
• If it is less than 1.000, then it pulls the bend towards the straight line.
• If it is bigger than 1.000, then it makes bigger slope on the chart.

I'm adding these comments to contract to be clear
