One minor thing: Recently, I uncovered that around 5% of the legacy code I was using was based on the wrong Date variable starting from its SQL pull. One of the variables was EnteredDate and another was EffectiveDate, I kept getting duplications using EnteredDate , so I dug around the organization and found someone who said "Oh, I always use EffectiveDate". I had to re-run models and tables, the faulty code was an important variable-builder for my multivariate logistic regression models, so I needed it to be 100% accurate.
