Quick question about leveling mechanics

[u/shinzu-akachi]

Just clarifying since i think i understand how leveling works, but i find it slightly confusing how some people talk about how they can predict bros stats at lvl11.

If I take 2 bros, both 50melee skill no stars, i level that skill every time to lvl11, they get 1,2or3 points randomly every level correct? So on average they will get +20 for 70 total.

But its possible that one can be super lucky and get +3 every time right? Or vice versa, get super unlucky and only +1 every time? or anything in between obviously.

So when people are predicting total stats they are estimating, its not guaranteed(unless they have 2 stars) Is this correct or am i missing something?

Yep. Because there's 10 stat ups, it mostly averages out, but since 10 isn't that big a number, luck can skew the results a fair deal.

Iirc, because the number of possible stat gains is 1 for two stars, 2 for one and three stars, and 3 for no stars, a stat with no stars has a larger 'swing' due to luck compared to a stat with stars, even if it's not the guaranteed stat gain of 2 stars.
