Hardpoints just show what and how many of each weapon type can be mounted. Whether or not you have critical slot room depends on what weapon you want, how you fit it, and tonnage restrictions.

In a 280 engine, think of it as 10 invisible free weightless HS that belong to the engine, and then there's a 2 crit "slot" that can hold 1 extra (weighted) HS per 25 engine rating.

So in the 280, you have you 10 free invisible HS hidden in the engine, and then you can choose if you want to shove the 11th in the HS crit mount or not. If you choose not to, then you keep the free tonnage.

So in theory, you could run a 400 engine and put 6 extra HS in it, and they wouldn't take up any extra critical space, but would still add 6 tons to your total weight.
