Yes

Yes, it is still recommended to still use an unported cylinder. The cylinder porting is not that precise and there is quite a wide tolerance margin taken in to consideration with the recommendations.

By increasing to a 590mm inner barrel, it is recommended to upgrade to a bore up unported cylinder.

True

I suppose, but you are not taking in to account other (external) forces. Hence, why such a wide margin of tolerance is considered in the recommendations.

False. See above. Also, the area of force applied to the surface of a spherical object does not change linearly as you have indicated. See some of the formulas in the earlier part of this thread.

English what?

Are you referring to your imaginary scenario or real world?
In any case, why are you concerned about a non-realistic scenario? Why not just stick with what's tried and proven?

See above.
