To do that, all you need is to add another field to your form which will hold this default - minimal value.
For example, to do that, you would need to add a text box field with a default value set to 5 and then add it in the Form Calculation as so:
I did have to make an adjustment in your Form Calculation (under advanced settings) to not wait for the change in the fields to do the math, but to start doing the math automatically since 5 would be hidden and never changed.
Do let us know if you have any questions in regards to this and we would be happy to answer them for you.
