Using 2D12 instead of 2D6 presents at least two advantages: DMs are less constrained, and TLs (after adjustment) become potential target numbers.
Tech Levels in 2D12 Traveller are a compacted form of the "normal" Tech Level scale.
In 2D12 Traveller, one use of TL is as a target number for technological tasks, such as firing ship's weapons, or the abilities of robots or programs to actually perform a task. This is what I use to determine where the Imperium is on the 2D12 TL scale.
Assuming a ship's computer in the Third Imperium laser has about a 40% chance to hit its target, and we use 2D12 <= TL as the task success, then the Imperium's TL15 would be at Adjusted Tech Level (ATL) 12. On the low end, I will guesstimate that TL 9 is ATL 9.
Compressing 4 ATLs into 7 TLs cannot please everybody. With that in mind, here goes.
