Parametrised blueprint mat selection formula

[JustSmile]

I need a tip on what formula to use to parametrise requested mat amounts for a requester chest tied to an assembler's recipe to emulate vanilla behaviour when copying the recipe onto one; that behaviour being chest requesting enough for multiple crafts with short craft time and enough for one with long craft times.

Using (1/(p0_t/30))p0_i1 gets me close enough for most cases, but when using it for something like an Mk3 module it'll request 0 of some materials since it divides 1 by 2 and rounds down.

If I go up enough for a 60s recipe to request enough for one craft, some expensive recipes get TOO requesty.

Essentially, what I want is for the recipe to request (1/(p0_t/30))p0_i1 OR just p0_i1, depending on which one is larger - but I don't know if it's possible to express in a notation Factorio parametrisation UI will be able to parse.

This is the current design:

How? I don't see a way to feed the selector(or any other combinator for that matter) values such as recipe crafting time or each ingredient's amount from blueprint parameters.

With that said, I figured the issue out. Will leave it here for posterity - the formula is

max((1/(p0_t/20))p0_i1,p0_i1)

with variables and exact numbers adjusted to need.

Ohh~ U can do it that way too~ Nice~ I just use multiplication machine and set it as M for multiplication and then set it as a variable. When I plomp it down I get a prompt for the recipe and a multiplier for the request~
