Technically, I believe the rules don't actually admit any allowance for
overage; a design that can't be brought below 101 tons must be treated as a
200-ton design. However, dating back to the LBB days, there's been a _de
facto_ allowance; at the moment, I don't recall whether that allowance was
10% or 20%. Can someone enlighten me, please?

From the Traveller Book; "Finally, a leeway of plus or minus 10% to 20% should be

allowed. If the final deck plans come within 20% of the

tonnage of the ship specifications, then they should be

considered acceptable".

That is for deckplans, For commentary on designs them may be some commentary in T5 but I am at a loss to point you directly at the relevant section.
