You don't multiply, you divide.

I suggest using 0.02/rate to get weights.

I use these values, in FTDNA order, for the 37 FTDNA markers:

22
6
14
7
11
7
80
50
5
10
18
8
4
24
14
70
90
6
14
11
3
8
7
5
6
7
7
26
12
4
4
3
3
2
2
7
23

and for the SMGF markers:

441 18
444 8
445 25
446 8
452 14
461 10
462 44
463 15
1B07 25
A10 6
C4 10

Some people might want to set the weight for the very slow
markers to a lower value, like capping them at 40 or 50.
