What do you think about assigning a local overage variable directly in #mass, rather than the method call. Names are good, but extra indirection can be bad, and the fact that you have to thread the mass variable down to this private method is a point against IMO.

You mean in #calculate_points?

That's fine by me...

I think it should be a separate refactor though.

So far, the ruby one uses the same format.

Something to fix later, not to hold up this PR...

Wait, why do these methods exist more than once? Can't they be shared on Base then?

Yes +1

I guess the overage method could already by shared innocuously.

The calculate_points method hasn't been moved yet because 2 of the 4 languages use the old calculate_points formula (base * mass)

Is that intentional? Is the card you're working on fix "Duplication" or fix "Python"?

ATM I'd say Fix python-duplication which is the child of Fix python.

We've been tackling grade tuning on a per-language basis, descending into the language's engines.

Not sure if that's the best approach.

Where's mass_threshold? Did you mean DEFAULT_MASS_THRESHOLD here?

No, you can also set a custom threshold.

The method is inherited.
