Accurately inaccurate 

The expressed measurement wasnt at scientific standards. The rate of change between measurements at different time points showed a precise rate of change.

My total body fat measurement wasnt accurate on the scale. But my rate of bodyfat lost was. My scale is Accurately inaccurate.

proportionally inaccurate 

A person who when you see them looks built strangely. This does not apply to people with any form of disability or a midget. Someone who is proportionally inaccurate looks as if when god was creating them he skipped a few steps or messed up when doing the math to find the right proportions.

My math teacher kinda walks funny. I think it may be due to her proportionate innacuracy. Shes proportionally inaccurate

Inaccurate Conception 

The act of God impregnating Joseph instead of Mary

God-"Shit dude, look what I did, Joseph just looked more appealing."
Mary-"What the hell."
God-"I'm gonna betch slap you, shit bag."
Mary-"Okay"
God-"...It was just some inaccurate conception... NOT!"

cycle inaccurate emulation of their religion 

(From software emulators where the processor chip instructions were skipped if they weren't practical/necessary to be emulated)
1. The way any "nonstandard" religion operates today, when compared to back in the days of greco-roman or medieval europe times or the common stereotypes. A cycle accurate Aztec would capture people, sacrifice them to the Sun and eat them. To emulate the Aztecs today would require cycle innacurate emulation because cannibalism and human sacrifice is illegal. Likewise Satanists today are cycle inaccurate because they don't sacrifice goats. Wiccans today are cycle inaccurate because they don't hex their enemies or worship demons. Catholics are cycle inaccurate because they don't burn women at he stake anymore. Being cycle inaccurate is not necessarily a bad thing. The decision to be cycle inaccurate is because of practical and legal reasons.

There are probably people who call themselves Aztecs or Mayans, but that's cycle inaccurate emulation of their religion.
