I think there are mods that enable all quality at the start. Although I've not tested them with my mods. Currently away from my computer so can't really test.
I do agree though spacing out the science so mythic comes from aquilo. In all honesty the recipe cost was where I was laziest in the mod just copy pasting them then multiplying the numbers.
So definitely a change I will make as the new default but I will add the option to set it to what it is now for people who would prefer it this way.
Also I do intend to make a mod where you unlock the extra tiers of quality by making specific products of the lower tiers. Rather than traditional reasearch
