I am entering a brief LitRPG arc, some of my character's feat are hard to calculate, to me at least. The MC is at least Large Country level to Continential.
Some of the things that she can do normally:
-She has what is similar to Ultra Instinct, she sees the world in numbers and formula and is able to calculate them, in dnd term, it correlate to Wis or Int. What number do you assign to hyper instinct?
-She hit like a train and is able to lift up to 5,000 tons.
-Her charisma is so high its borderline mind control without using her special powers.
-She pretty much have near infinite stamina, able to fight demigod dinosaurs faster than the eyes can see to a stand still.
Things like this, how tf do I translate these feats into number?
Okay, so as I understand, first bit of advice: no, the numbers mean nothing.
I've read enough stories where authors tried to quantify how much exactly one point in strength or in stamina was. Without any exceptions, they were stupid, whether they tried to set an average for humans or directly quantify something like one point in strength allows to lift a certain weight. Those numbers only somewhat make sense with stats such as Mana, which can directly translate to the size of the mana pool, but even then it gets funky when you go into details.
Numbers should generally be arbitrary, mainly because it's just impossible to properly put some things into numbers - human bodies and minds are far more complex than that.
I believe what you should focus on is two primary things. One - how stats work, or what they represent. Generally, are they the strength of magical enhancement? An overall representation of something? Right there it's also really helpful to separate stats into expendable resources (health, mana stamina, whatever else) and values (strength, agility, intelligence, etc.), because values may start at zero while basic resources shouldn't.
Two - how stats scale. Linearly? Exponentially? Most people don't really take this into account and it ends up pretty arbitrary, but it's at least useful to make a distinction between linear scaling and non-linear scaling.
Probably the best way to go about it is to set up some references. For example, show stats at level one, which is a rough reference to average strength, and go from there, gradually increasing the numbers as the character grows according to the scaling you choose, and keep consistent with it. You can give a glimpse of the stats of a god, or someone strong, so the readers will know how close your mc is to them, and you'll have a reference that will keep your urges in line.
Now, from there:
Ultra Insctint - this should be either a skill, or very high perception, or a further generalization. Can't tell you anything more, because virtually anything will go so long as it's consistent.
For example, if your stats are an overall representation of a character's strength, you can just give the character very high Perception stat. That stat itself won't include what kind of perception it is, but remember numbers are always a simplification.
Another solution is to consider this a skill. You can leave stats unchanged and give the character a passive skill either without a directly specified effect, or you can say it increases perception be some number and percent.
Strength is just a stat. Don't get hung up on the exact number, since it doesn't really matter anyway. You can come up a rough equation that turns strength into how much strength someone can exert, but realistically strength depends on far too many factors for it to be accurate beyond rough estimations.
Charisma... well it's high charisma, what did you expect. The exact number with mind stats becomes even less meaningful than with physical stats. This here, though, usually is better dealt with as a skill.
Infinite stamina... there's a lot of ways to deal with it, because this is a resource not a static value. You can give her a huge pool, you can give her very quick regeneration, you can give her skills that... do something that keeps her stamina high.
Notice not in one of the four I gave you any numbers. That's because they don't matter much. Consistency, is what matters the most.
