DIY Liquids not measuring correctly

LOL

Don't get mewrong. Doing Accurate DIY is Good Thing. But there does come a Point where you can be More and More Accurate and NEVER tatse the Difference.

It can become an Exercise in Futility and can lead to Frustration.

The Retail DIY Mixers I know talk about a +/- 3% Accuracy as Completely Expectable.

I also believe in being as careful as possible (both in measurements and safety precautions) but I have to add that with the equipment most of us use, you can be more and more careful without actually increasing your accuracy at all. If you aren't really familiar with the technical definitions of accuracy and precision this can be a counterintuitive concept to grasp, I think. There simply comes a point in any process that involves measurement where you reach the limits of accuracy and more care (or 'anality'- LOL) is just wasted time and effort.

Agreed. I always try to measure as accuratly as possible, but that one or two drops in a 30 ml bottle aren't gonna make or break me. And I can always tweak it later.

I completely Agree.

Many people think these Two Concepts are Interchangable. They are not. Here is a Simple Graphic I use to Explain the Concept of Accuracy and Precision.

Very nice visual analogy!
