Imputation of 1/5 of the minimum values for missing values

Hi. I am just wondering if there is a reasoning behind imputing 1/5 of the minimum values for values in a group that are missing. Is there a reference? For one of our projects “we imputed 1/5th the minimum for any missing values”.

Thanks.

This is empirical - computed for each variable as a proxy of their detection limit
