oh i get it, the frequency of use is what allows frequency analysis.

use a pad once then rotate to a new pad. [effectively re-key the encryption]

avoid using characters in high frequency [vowels, language specific phonemes]

use alternate misspellings, intentional typos.

keep the message very brief, the longer the message the more effective frequency analysis becomes.

try to avoid corelative events.

if every time a cypher that looks like [abc] is captured, somthing, is bombed, or major troop movements occur, you have an idea what the message is about, giving a bit more leverage.

also standard OTP pads use 2 axis, a tensor matrix is a better OTP.
