Base calcolo sconto %

Hi, I bought your plugin, everything is ok but I have a problem.

I want to show the price table with the% discount.

However, when I set the price ranges, the plugin applies the discount to the sale price and not to the normal price. So, if I have a product like this:

normal price 100
selling price 90

from 2 pcs 20% discount
from 5 pcs 30% discount

the table shows me

1 pc = zero discount = 90 €
2 pcs = 70 €
5 pcs = € 63

because it offers discounts starting from 90 € (discounted price)
instead it should start from 100 € and then

1 pc = zero discount = 90 €
2 pcs = € 80
5 pcs = 70 €

I also tried not to enter the sale price, but the system does not let me enter the quantity 1 as the first range ...

So I'm stuck and I had to import the prices with the fixed price method but the fact that you don't see the% discount we apply on the frontend is not good.

Is it possible to add the option? That is to make the user decide if he wants to start from the regular price or go up to apply the discounts?

Or have the option to leave the sale price blank but add 1 pc as a range?

Thank you
