Letter frequencies, English Language for Letter Beads

Do a search on "letter frequency" or "english letter frequency".
You'll find charts that break down the letter frequencies. I did a bunch of searching last night, and most of the charts agreed, with minor (less than 1-bead) variations in lots of 100 beads.
You can use the 1000 word frequencies, divide by 10, and use the whole number to pick the beads, or you could use a letter frequency grouping, where E is most common, T is next common (unless the words don't contain any "The", such as names), and so on.
I could not find any breakdowns for names, specifically, but using a list without "The" would give you a pretty good breakdown.
Here is a brief quote from a public information site:It will be noted that the letters, when arranged by relative frequency,
fall into certain well-defined groups.In short messages, and in all text where there are less than 1500 words,
any letter in one of these groups may show a higher frequency than another
letter of the group though in text consisting of more than 200 words a letter
rarely shows such frequency or infrequency as to fall in the wrong group.For convenience' sake the groups may be listed as follows:I E
II T
III A, O, N, R, I, S
IV H
V D, L, F, C, M, U
VI G, Y, P, W, B
VII V, K, X, J, Q, Z If the word "the" is omitted from a given cipher message, T drops into the
third group and H into the fifth."I E
III T A, O, N, R, I, S
V H D, L, F, C, M, U
VI G, Y, P, W, B
VII V, K, X, J, Q, Z
I find This to be an over simplification, since Z is the most uncommon letter, even more so than Q. Although, in NAMES, it might be the other way around. I tried to do some brief analysis on some name databases, but got sort of messy results.
Another summary is:Order and Frequency of Single Letters
E 12.31% L 4.03% B 1.62% T 9.59 D 3.65 G 1.61 A 8.05 C 3.20 V 0.93 O 7.94 U 3.10 K 0.52 N 7.19 P 2.29 Q 0.20 I 7.18 F 2.28 X 0.20 S 6.59 M 2.25 J 0.10 R 6.03 W 2.03 Z 0.09 H 5.14 Y 1.88 Letter Groups Percentages
A E I O U 38.58% L N R S T 33.43% J K Q X Z 1.11% E T A O N 45.08% E T A O N I S R H 70.02%
