errorless
Without any flaws
Errorless means without errors or mistakes: an errorless performance, errorless learning.
The word appears most often in technical contexts—sports statistics tracking errorless innings or games, educational methods designed for errorless discrimination training.
In casual use, flawless or perfect are more common choices.
