Uji coba lima huruf yang paling diminati diujikan pada artikel berbahasa : Bahasa Indonesia, Sunda, Jawa, Jepang dan Inggris.
Berikut ini adalah hasil screen capture dari masing-masing bahasa yang diujicobakan :
1. Bahasa Indonesia
2. Bahasa Sunda
3. Bahasa Jawa
4. Bahasa Inggris
5. Bahasa Jepang
Berdasarkan percobaan dengan menguji 3 buah artikel yang berbeda untuk masing-masing bahasa, diperoleh kesimpulan lima huruf terfavorit (dari kiri ke kanan) adalah sbb :
1. Bahasa Indonesia : a, n, e, i, k
2. Bahasa Sunda : a, n, g, i, r
3. Bahasa Jawa : a, n, e, u, g
4. Bahasa Inggris : e, t, a, s , i
5. Bahasa Jepang : a, o, i, t, u
jadi huruf yang paling diminati adalah huruf “a”, kecuali pada bahasa inggris most wanted word nya adalah “e”.
