Ultra-tech (page 8) provides a variety of TL progressions:
Code:
TL Accelerated Fast Medium Slow Retarded
9 2020 2025 2030 2040 2050
10 2050 2075 2120 2200 2500
11 2100 2200 2500 3000 7000
12 2200 2600 4000 8000 20000
It seems unlikely that we're going to hit TL9 in 17 days time, so we're probably not on the
Accelerated path.
Fast might still be reasonable so changing the start date to 2200 might be reasonable, meaning the setting is on the cusp of TL11, with very mature TL10.
