OCD opinions- good or bad?

@joshuadusk The main thing I have noticed so far is that a small amount of coffee seems to get stuck to the bottom.

I was curious about it so I tared my scales, ground coffee into the portafilter and checked my dose, then used the OCD and tamped and rechecked the weight.

On many occasions my dose went up or down by .1 or .2 of a gram. I’m a bit put off by this as u can’t seem to stop it happening. The past week has been me pulling a few shots with it and then placing it on a shelf behind me for a while until it catches my eye a few hours later and I try again haha

If anyone has tips on how to overcome this problem or better ways to use the distribution tool, it would be much appreciated.

I’m also interested to hear others opinions and as Joshua mentioned if anyone has done any scientific experiments using the OCD
