Consistency custom fitness value

Hi everyone, I need your help, when I develop a new strategy, I would like to have a custom fitness value in the report that tells me if the profits are constant over time or are concentrated only in a few years of the sample period. Do you know if there is something like this? do you have any advice? Thank you

You may try sharpe ratio, or SQN

Thanks.
