Complex formula – upgrade to v4

Hello,

I would like to upgrade from version 2 to version 4 so everything works correctly on latest WooCommerce.
I looked at the new features and wondered if there is a better way to calculate prices with v4 for my purposes. I’ve been trying the demo, reading the manual, testing it on my testing server but frankly it’s over my head ;O].

I have 2 products-parapets with 4 options – color/material, width, length, caps

Product A
colors – same price for all of them (at least for now)
width – select from predefined sizes
length – text input (range 300-6000 mm)
caps – select from 4 options with different prices depending on width range

This way I have around 36 condition rules with only 2 caps present. Since I’d like to add 2 more it would take a lot more condition rules to have 4 caps.

Product B
colors – same price for all of them (at least for now)
width – text input
length – text input
caps – select from 2 options – Yes or No

Is there a better way to do this with v4? I have currently license for version 3 but I don’t mind buying version 4 Pro if there is a way.

Thank you for reading this far, any idea appreciated :O]
