Every time I do a mix.
I’m on board @Grubby.
@Grubby dam good idea all the toys on one link
I do use this calculator on and off intermittently with the ELR calculator depending upon where the recipes are that I want to mix but I very rarely use the ATF calculator as it just doesn’t meld with me and for some reason I don’t trust it.
I signed up for a few days, I’m still adding the aromas to my stash…if it looks like ELR I think I’ll use it, I still have to browse around here…
There’s a calculator?
