I'd make a new page in the Pokemon's info to hold this info to avoid cluttering the stat page. I'd have the base stat here as well for ease of info. Basically a totalling sheet for all numbers that make up the stat. Would also add the stat assignment interface.
>IVsNow generated based on Nature. Starts practice stats at a certain amount above and below corresponding to the nature. For example, +15 to one stat, -15 to another, with the baseline start at 0.
>EVsEarned by feeding berries. Berry growth cycles are accelerated by defeating, catching, hatching, leveling, and evolving Pokemon. Maybe berry pots in your pocket like FRLG. Natures double gains from berries for the beneficial stat, and halve those from the detrimental stat.
>Practice StatAfter a set number of stat points being assigned, cannot assign any more. Negative stats count in this calculation, meaning you can distribute a few more points to other stats or just get the negative one to zero.
Boom, individual pokemon, you choose their growth, you have a clear way to accumulate stats, you can bank them for new party members, you can do some fun tricks with numbers depending on how you set it up.
It's not flawless but I think it's a good way to adapt most of what we've seen and keep things familiar while improving the base.
