All I did was crossing a diamond with a pearl, but I find it fairly easy to do compared to the crude way or any other ways I thought of.
So here they are. x is the RC.
- 0.25D 4x
- 0.5D 2x
- 0.75D 4x/3, x+(x/3)
- 1.25D 0.8x
- 1.5D 2x/3, x-(x/3)
- 1.75D 4x/7
- 2D x/2, 0.5x
- 2.25D 4x/9
- 2.5D 0.4x
- 2.75D 4x/11
- 3.25D 0.3x
- 3.5D 2x/7
- 3.75D
01~08 x/4
09~23 (x+1)/4
24~30 (x+2)/4
- 4.25D
01~08 x/4
09~23 (x+1)/4
24~30 (x+2)/4
- 4.5D 2x/9
- 4.75D
1~10 0.2x
11~30 0.2(x+1)
- 5D 0.2x
- 5.25D
1~10 0.2x
11~30 0.2(x+1)
- 5.5D 2x/11
-When you divide by 9, the remainders become the repeating decimal points.
ex.)13/9 = 1.444 and so on.
-When you divide by 11, the remainder times 9 becomes the repeating decimal points.
ex)13/11 = 1.18181818 and so on.
-When you divide by 7, the following six digits repeat: 142857
Memorizing which remainder gives which decimal points helps in getting your TC quick because you won't be dividing; you'll just know which decimal points would fall.
-Keep in mind that when you divide, you can also do it backwards.
I think this is about all the tricks I know about TC conversion. The resulting numbers get along pretty well, and the difference is never more than 0.17 as I recall. 1/2D increments are no big deal, and with the verbal pointers above, they should be a breeze. 1/4D increments will require some practice to get used to. It took me about a week of going over 500 of them everyday to feel comfortable with every one of them as you know and I know that it's all a moot point if I can't pull it off. I still work on it everyday though at the moment I'm working on speed rather than comfort level. At any rate, should you come my way, you can share my poison wine.
Frankly, I'm not really sure why I felt like being Santa Clause typing all this number. Enough with the rambling. I hope you find it useful. May the cards fall in your way.
Don't lose the number, Rikki hehe
