Certainly this is not helping. However for the OP not typing in precise dimensions to begin with, and most importantly, failing to use groups or components to isolate geometry are both also big factors.
Certainly not the first time this has been asked, there is a well considered conversation about this subject here. General consensus is that at worst it’s completely useless and introduces errors and at best it can be useful in rare instances by knowledgeable users. Everybody and their dog agrees that it should be set to off by default. Why this simple change has not been made is a mystery.
