Tech Level Progression

The cost of tech levels in Stars! (doesn't include 10/level added cost, assumes normal||Tech costs):

Level	Normal	Cost
1	50 + 10/level
2	80 + 10/level
3	130 + 10/level	T1 + T2
4	210 + 10/level	T2 + T3
5	340 + 10/level	T3 + T4
6	550 + 10/level	T4 + T5
7	890 + 10/level	T5 + T6
8	1440 + 10/level	T6 + T7
9	2330 + 10/level	T7 + T8
10	3770 + 10/level	T8 + T9
11	6100 + 10/level	T9 + T10
12	9870 + 10/level	T10 + T11
13	13850 + 10/level	T12 + 3980 (T10 + 210)
14	18040 + 10/level	T13 + 4190 (T10 + 210*2)
15	22440 + 10/level	T14 + 4400 (T10 + 210*3)
16	27050 + 10/level	T15 + 4610 (T10 + 210*4)
17	31870 + 10/level	T16 + 4820 (T10 + 210*5)
18	36900 + 10/level	T17 + 5030 (T10 + 210*6)
19	42140 + 10/level	T18 + 5240 (T10 + 210*7)
20	47590 + 10/level	T19 + 5450 (T10 + 210*8)
21	53250 + 10/level	T20 + 5660 (T10 + 210*9)
22	59120 + 10/level	T21 + 5870 (T10 + 210*10)
23	65200 + 10/level	T22 + 6080 (T10 + 210*11)
24	71490 + 10/level	T23 + 6290 (T10 + 210*12)
25	77990 + 10/level	T24 + 6500 (T10 + 210*13)
26	84700 + 10/level	T25 + 6710 (T10 + 210*14)

As you can see, it's a Fibonacci series up to level 12, then itlevels out quite a bit. To get all 6 categories to TL26: (at all normal cost): 4,185,240

This includes the 10/level additional cost, and assumes all Tech areas start at TL0.
