Ok, thx for the video link. It does show a little how it works. Now, question:<p>How is this better than a notebook and or an excel file?<p>That&#x27;s what the people I know use (for years) and they hardly have issues with shifts. I even looked into building them a &quot;better solution&quot; because I thought I was smarter than them. But nothing I did was better that their own system.<p>By the way, I&#x27;m not grilling you publicly! Just really interested in what you came up with. :)
