The spreadsheet I still keep by hand, even after building software to replace it

I'll admit something a little funny for someone who builds monitoring software: I still keep one thing tracked by hand, in an actual spreadsheet, separate from FounderFlow.

It's a weekly gut-check column. One line per business, written in my own words, on what I felt was off that week even if nothing technically triggered an alert. Not data, just instinct.

I keep it because some judgment calls aren't ready to be automated yet, and I don't want to pretend otherwise. A few times that gut-check column has caught something before any signal did, a supplier relationship that felt slightly off before any numbers moved, a team member who seemed checked out before it showed up in any metric. FounderFlow is good at watching things that show up in data. It is not good at watching things that only show up in how a conversation felt.

Keeping that manual column honestly makes me trust the automated side more, not less, because it keeps me from asking the software to do a job it was never built for.

Genuinely curious for other founders running tools that are supposed to "handle it for you": what's the one thing you still track by hand, on purpose, because you don't fully trust automation with it yet?
