I don't think you understood the context of what I was saying. I was referring to the previous post.
Some have suggested before that it is not possible to reduce HS calculation time, because it is simply the time it takes your computer to load the sector you're jumping to. The time required to load the new sector is not related to how far away it is, so I don't think that is a real limitation. Calculation time also scales with ship size, which again would have no/minimal bearing on the time your PC takes to load the sector.
Now, I do agree that for calculating an actual HS jump, it would make sense that it took longer based on distance and on ship size.
